Imagine if someone actually tries to perfect deep fried coffee. Like a coffee company saw this and got really invested and determined to make it work and make it a legit thing
@Jon Beydler And it's so expensive it's ridiculous. Some people also drink coffee from Elephants poop and they are more expensive from Luwak (Civet) coffee.
In malaysia and vietnam, we roast coffee with butter. Its gives a wonderful oily, savoury finish to the coffee and a nice lingering texture. There's a couple of youtube videos if you search for butter coffee , hainan coffee or Ipoh White Kopi (how its spelted in Malay). they also roast it with sugar to give it a richer flavour.
I was going to say, I would wonder if frying in ghee would be better and I would try a higher temperature at least once but wonder if staying below 350f is important for staving off potential maillard reactions.
I'm not a brewing expert by any means so I"m not sure how it would relate -but I've deep fried quite a bit, typically there is a plateau temperature to get above to avoid the food from just saturating with oil, different oils have different temperatures obviously, but if I were going to try this, contrary to what others have commented, I would try a hotter temp and probably use peanut oil. If you find the hotter temp cooks too fast, maybe pre-warm the beans in the oven or something. There is a point with deep frying where you can't just cook at a "lower temperature longer" you have to precook before you fry at that point.
I think another problem is that it seems that they're actually dehydrating the bean over actually cooking it, so I think you would have to do the opposite, high temp deep fry, then finish in the oven, I can't really solve that the goal is to make the bean more pourous by frying, while dehydrating Frying is by nature for sealing up and keeping moisture in,
@@phartferd5738 i feel like wayyy more trials need to be done cause yeah, what everyone who roasts coffee *expects* is for it to be dehydrated and porous, but it may not be a hard requirement i think we just don't know that more moisture is that bad, because the coffee industry has always bean- sorry been into traditional roasting but i am not an expert and thus talking out of my nether regions
I saw a dude fried coffee with butter and chicory in a wok while I was walking around Saigon a few years back. He was kind enough to grind up a fresh batch to brew a small cup for me to try with some condensed milk. it was the best coffee that I have ever tasted.
I think the oil temperature is a factor as well here. Typically for dried products that you want to "puff" (like puffed rice i.e.) you have to go way higher, at around 190°/200°C. With proper temperature, the oil penetrates way less in the product in general, and you might get a closer result in terms of cracking and size of the roasted bean
But with coffee, wouldn't those temperatures begin burning the beans? Even water above 190/200 Fahrenheit cause damage to ground beans... outside of espresso, where you essentially burn it up.
There's some literature that contradicts this. They posit that high temperature oil makes bigger cavities in the food as it boils the water away more forcefully, which then fills with more oil than a low temperature fry does.
@@LordWhirlin You misunderstand what Andrea is saying. She meant 190-200 ºC, which is 374-392 ºF. High temperatures are required to roast (or in this case fry) the coffee beans. I'm not really familiar with the chemistry behind it, but what I'm guessing is that boiling water (~212 ºF) doesn't really burn the coffee, it just has a stronger extraction power, and therefore extracts more bitter compounds, causing the coffee to taste "burnt". That can be supported by the fact that cold brew coffee has a much more mild flavor and less complex, because the cold water can't extract some compounds present in coffee. The case of espresso actually adds more factors, not only the water can be over 212 ºF, but it also goes through the grounds under pressure, causing it to leach very hydrophobic compounds that don't usually get extracted due to their low solubility in water.
You mentioned a vegetable taste, you can purchase oil extracted from coffee beans. I'd be curious if that would be something you could use to fry the beans and see how that tastes
I have a suspicion that what is happening in the filter brew is that with the unpressurized coffee draining down, the oils are able to float to the top of the slurry and sit on top of the bed rather than draining down with the water. It also explains why the resulting bed looks the way it does n
The oils are also absorbed by the filter itself, It would be interesting to see what happens if you were to use something like a Chemex filter that'll isolate a lot more of that end product.
Good point. Further to this, oil and water are immiscible, they repel each other. If the V60 filter was pre-rinsed with water, the water held by the filter would do a lot to resist the passing of the oil. You might get a very different cup if you didn't rinse the filter beforehand. In the espresso shot, this would likely not have mattered since there's an immense amount of pressure forcing everything through.
As a roaster/owner of a Roastery (Swamp Donkey Roastery), I appreciate your experiment, although I would suggest if you were to try it again, you go with a much higher oil temperature. While that may seem strange, I believe the beans spent too much time cooking in the oil, thus absorbing much more oil then they may have with a higher oil temperature. I would suggest an oil temp that would develop the bean in the 6 to 8 minute timeframe, I am sharing this thought as we roast in a Scandinavian Profile, very high heat in the beginning (neighborhood of 600 +/- degrees f w/a drop in the 400 +/- degrees f) of the roast, allowing the bean to go through first and second crack in about a 6 minute plus timeframe w/o tipping. The quicker development in the temps we utilize seems to reduce/eliminate undesirable acidity and bitterness while not caramelizing all the sugar in the bean for a much sweeter full flavored extraction, based on our experience and customer feedback.
The weirdest way I've made coffee, according to a very old recipe, was to let the beans soak in cold water for a few hours and then to put the full beans in a French press and pour hot water just below boiling. It ends up tasting like if coffee was tea.
I'm sure the type of oil would make a huge difference in taste, but I actually want a part 2 trying to roast in different substances like butter/sugar/honey/vanilla/cream/etc.
What besides butter most them cant really be used to roast somthing suger is solid not sure boiling honey is going to cook anything and cream will melt snd vanila exstract is mostly a mix of alcahol and water its got a lower boiling point than water tho so it just boil it not roast it
If you ever decide to try it, use a French press. If you don't like it, you can use the french press to make tea instead! It's an old invention, but it's waaay smoother than the burnt taste that drip coffee or teabags make.
For those of you that don't already follow James and had this randomly recommended, this is the level of energy he brings to all his content. I personally have been following for quite some time and its hard to fault any of his work or find another person with equal passion and educational content for coffee. I encourage you to watch his content it gives a new paramount meaning to coffee in many aspects.
I don't drink or really care about coffee really, got this recommended and clicked it because of the sheer weirdness of the concept. It's a really well made video. I don't intend to watch any more coffee content, but I must respect him and the way he did this video.
Deep fried coffee, or fried coffee, is pretty common in the preparation of kopi (southeastasian singapore/malaysian style coffees). It's usually fried in a wok, then filtered through a coffee "sock" and then poured over in glass mugs. There's variations with different coffee strengths and ratios of coffee : water and also using evaporated milk or condensed milk as sweeteners (similar to vietnamese coffee)
@@pagalmasala kopi and kopi luwak are two very different things. It's like caramel and caramelized onions. Just cause they sound similar or rather are described in the same way, doesn't mean they're interchangeable
Probably hasn't tried it but is likely aware of it as it's the same principle as the air drying process he described. I found out about drying coffee this way trying to find a manual for my popcorn maker.
Right. This is my problem. It isn't right to use an unhealthy oil. If you want gourmet, herbal material with all its miraculous phytochemicals, and natural magic, please for the love of all that is holy, fry it in something that is benign. Vegetable oil is terrible for you. And for the beans
I'm interested in avocado oil or coconut, although, coconut might have a strong taste to be used. Avocado is very tasteless. There's also things like mustard oil, kinda want to try just for the knowledge.
C8 MCT coconut oil, if you're going to do a bullet proof coffee. For myself, I'll just stick with air roasted coffee. However, this does get me thinking about other methods of roasting coffee. IR lamps perhaps?
Honestly, if you've got something you've described as "good" when it's your first shot at trying it with equipment that's not designed for it, you might have a winner on your hands. Remember, your technique is only going to get better, and you've got variables you can play with in terms of frying times. An even roast through the whole bean has to be a fantastic starting point. I would suggest that the reason the filter coffee works is because any remaining oil is floating to the top of the water as you apply it and is then just sitting on top of the bed at the end instead of making its way through the filter, so you're unwittingly filtering it in two different ways at the same time. I don't think there's a way to replicate this effect by espresso, and that's fine.
I do think there's most definitely room to explore this further, but as I don't own a deep fat frier I cannot partake! Specifically regarding the espresso, I wonder if stepping back in time a little might help with the observed acidity and harshness: Dosing high and pulling short, like we did back in the 90s to make some of those harsher espresso blends more pleasing with (fatty) milk serves. Most interesting to me was the consistency of the fry: Whilst bean to bean was clearly not very consistent at all in this small frier, I wonder if (as it often does with roasting) scaling up would remedy this to some degree: Anyone fancy chucking half a kilo in their kitchen's Thor? :D
James guessed at the frying temperature. The lack of cracking makes me very curious if his oil was hot enough. He acknowledged that his grate was too coarse and let a lot of beans fall through. So many ways this could be "dialed in." In fairness, I've never roasted coffee. Give me a coffee roaster, of any type or brand, and I suspect my first batch would be horrible. Maybe fried beans have no place in an espresso machine, but I think it would be very interesting to experiment and dial in for pourover. If the first attempt was "not bad" that suggests good, if not great, is achievable.
Great video. Your reaction to the filter brew was brilliant. 😂 The struggle to try to come to terms with your creation brought a smile to my face. The espresso reaction brought tears to my eyes.
almost gothic in a way, it was frankenstein trying to realise that his set goal was attained, but he was never prepared for it that way, the success feels more grotesque than any potential failure
I have a friend in the US who has said for as long as I have known him “if you can’t cook it in a deep fryer, it’s not worth eating”. I am making sure he sees this.
The initial observations in this are super interesting to think about in comparision to experiment of deep-fried vs air fried food or how to layer fats in a sauce without over doing it so it feels greasy. I wonder if there is a sweet spot that could be achieved through convection roasting with a small amount of oil on the beans for the espresso pull to get that same rounded off flavor that was good in the filtered coffee without the oily feel. If you ever do some follow up experiments and need an extra taste tester let me know!
I do think that coating the beans in oil might help develop an interesting "bake on them". My concern would be how bitter would they be when that happens!
Having followed your advice on how to get the best out of my little Bialetti, I am now having the best early morning coffees I've ever had. I think it wise to continue this attention regarding your comments on deep frying the beans. Many thanks for an entertaining and amusing experiment.🙏💜
What I love about James is that whenever I have a silly idea that I'm almost embarrassed to say out loud I know that he's somewhere having an even sillier one
And that is a Researcher in a nutshell . Trying out the potential ways to make something happen and then creating the recipes we will be eating from in several years! 😁
Loved the video. Especially the . . . "it is a weirdly nice cup of coffee". I appreciate you experimenting with alternate ways in the coffee experience. Another interesting variation to try. 👍🏻👍🏻
a few recommendations from my roommates and I: from my own experience as a home cook: i’ve filtered/clarified oil on my own with a variety of meshes and filters, and i know coffee moves through a coffee filter significantly faster than oil. your pour over cup may have been less oily because of the paper filter from roommate 1’s experience as a fry cook: even if you have your frier at a high temp, if the item you’re frying doesn’t sizzle upon impact, you need to increase the fry temp. the reason why fried food isn’t chock-full of oil is because of the force of the water evaporating and pushing back against the oil. in his words, “even if you increase the tempurature after putting it in, if it’s been frying without sizzling it’s too late.” his recommendation was to increase the initial fry temp and then decrease it to your preferred tempurature after a little bit. from roommate 2’s experience as a science nerd: there are substances you can use to extract the oil from things, so maybe you should do that to your espresso either before brewing or before drinking. i’m not clear on how this last recommendation works or what you’d have to look for because i don’t understand chemistry really.
For the last one you could use something like a couple DCM or ethyl acetate washes, the problem is that a lot of the flavours in the coffee aren't particularly polar either, so you are going to extract them as well. For example caffeine is also DCM and ethyl acetate soluble so some (many cheap/bad) decaffs use those washes for their process. In other words you're gonna end up with a much more flat decaff-like tasting end product.
If what you are trying to fry, has no "water", then its not going to sizzle much, if at all. If he pre-wet the beans, then the beans would have that mini "steam-cook" effect in the oil, in the same way that a French Fry would cook in the fryer.
@@johndough8115 Water is one of the "stickiest" materials. In a vacuum, you could be down to 0.0001 atmospheres and there will sstill be water. In other words, there will always be a sizzle.
The fact that it turned out quite nice first try, on some random settings (given that there's little known about how to correctly deep fry one's coffee beans) makes me think that with a bit of experimentation this could be a legit method.
Air fryers are absolutely capable of roasting but you need the beans to be constantly moving which I’ve never seen on common air fryers Edit: I stand corrected. Some come with rotisserie baskets which might allow you to keep the beans moving enough where they can roast evenly. If you have one it's worth a shot but if you don't want to spend a lot of money to try roasting your own you can try the cast iron method or check out your nearest thrift shop for a popcorn air popper. I used one of these and got 50g coffee done within about 7 minutes and they tasted pretty good.
From a Barista's point of view, this is amazing, and I love learning newer thing's ❤️ . It's interesting to see the beans in the deep fryer . Thanks for the information and awesome video 😮
In Singapore we have nanyang style coffee where the beans are roasted with butter and sugar. But it’s usually roasted dark and brewed using suspension and a cloth filter. I believe this method was developed to work with the coffee grown in Southeast Asia. Somehow grease and coffee works lol
Roasting with butter/margarine and sugar is done to improve the taste of the more bitter robusta beans that are used in kopi and other SEA coffee. (International specialty coffee basically never uses robusta since robusta can't match the taste of arabica beans, which are a lot more expensive.) That said, roasting with a fat is very different from deep-frying with it - the medium of conduction is air vs liquid fat.
I was looking for this before commenting about it myself! I've heard about people doing it the opposite way, too, using butter to fry up coffee beans super lightly. I dunno if this is a misinterpretation of a more traditional style or not but I've heard it referred to as "white coffee".
My great-grandpa had his own recipe involving the use of butter, sugar, and the previous day’s roast (although I suspect the latter is just his way of cutting corners).
This one of the funniest videos I have seen in a while. I love how professional he is while dealing with something this ridiculous and how genuinely surprised he gets when it actually turns out good. The fan part was my favorite 🤣
This reminds me a lot of “Nonya coffee” in Singapore & Malaysia! They roast the beans in margarine before grinding & brewing it in a large “sock” (very similar extraction style to filter). It’s drank widely with a bit of condensed milk or sugar - but many people also have it black with with some water. I’d describe it similarly to James did here. It’s coffee but without the complex & interesting bits, and the flavour is much rounder, softer, & less acidic! Crazy stuff
@@thepenguin9 Yeah, but you want the ones with expeller-pressed oils like found in organic margarine (Earth Balance, Smart Balance), non hydrogenated ones like industrially-processed margarines (Country Crock etc).
I think the reason why the "pour over" one tasted better was that the deep fryer oil had time to rise to the top and was left there due to density differences. While the rest of the coffee's goodness drained down. On the other hand, the espresso machine uses pressure to push down all the liquid contents and also pushes most of the deep fryer oil mixing with the shot. In that process, it then overpowered the coffee, making it taste not very good.
I love how he tastes the first coffee, and we're treated to 15 whole seconds (including a jump cut, so it was probably lonter IRL!) of James just being a physical incarnation of the "visible confusion" meme.
When people deep fried the food, we normally deep fried it twice, the first time in a lower temp say 160-165c to cook the food and the second time in a higher temp say 175-185c to push the oil out from the food. If you skip the second step, the food will be very oily. And this is also what happened in the video.
considering how you could taste the vegetable-ness, makes me wonder how other types of oils might pair with certain types of beans, like ghee (type of clarified butter that's cheap to make) might be an interesting combination, and the ghee itself will have an interesting flavor too lol
that vegetableness may come from some raw part of beans from inside too. cooking with oil will transfer heat faster and everywhere, when you roast it some of it may be raw inside.
This is a shot in the dark, but I think the process of making filter coffee also does a good job of filtering out the grease. It's going to float on the top during most of the brew and get trapped by the bed during the drawdown. The paper might help as well. With espresso you're forcing all the grease the other side, you don't get this gravity aided density separation.
I think the same too. With espresso you kinda brew the coffe with higher temperature (steam) along with higher pressure. The heat makes the oil kinda melted/less viscous and pressurized to pass through the filter. That didn't happened with manual brew because the melted fat will most likely stuck to the paper and not enough pressure to push it pass thru that paper.
On reflection, I’m thinking the oil in the V60 probably floated to the top of the bloom and were “filtered” by the grounds so that it remained in the filter. With the espresso, all those oils were pushed straight through into your shot. As always, thanks for taking one for the team so we don’t have to.
@@goncalovazpinto6261 hot water being poured through it could easily cause enough turbulence to make some stick to the filter. It takes a bit for oil to fully form a separate layer when it's mixed up
@@mrastleysghost I don't think so. The first thing that happens is that the filter gets wet. Once the filter is wet it will repell water and only let water soluble stuff through. When you start poring water, you specifically avoid causing turbulence, that's part of the V60 technique. Also, any amount of oil, however smal, will rise to the top and form a film. Whem the film is very thin it looks like waves of blue/yellow lines on the surface.
@@goncalovazpinto6261 What are you on? Passage across an unstirred water layer is rate limiting, but not an impenetrable wall. Pouring water will cause turbulence, V60 is no exception. Oil will rise to the top, given time and low turbulence. Before that, it's suspended and subject to all sorts of motions. You express yourself in absolutes, whilst chemistry is much more nuanced.
@@Karius7 And yet, the filter coffee was "good" and the expresso was "oily". Chemistry is science, i. e. building predictive models. V60 is an extremely gentle pour, also the water has to go through a mostly undisturbed bed of coffee grounds before it reaches the filter. I don't know if it was the case this time, but often you wash the filter before the coffee even goes in. If I wasn't nuanced enough for you it was for the sake of conciseness. Some oil will pass, not enough to change the flavor significantly: It is also a slower process than the expresso, so more time for the coffee grounds to interact with the hot water. Probably the bloom also has some effect on the separation of the oil from the coffee (no bloom in expresso). Also the crema in the expresso might be carrying most of the oil. There. I used "some" "enough" "significantly" "more" "probably" "might" and "most". Nuanced enough? 😁
Chemical engineer and former DIY coffee roaster here, just a couple of notes. -Caffeine is technically soluble in oil. I'd be curious what the caffeine content of that oil was afterwards, especially if you did this regularly :D -The beans had a very wide distribution of roast levels, all the way from City(minus) to almost French. I ended up with something similar back when I was using a cheap popcorn popper to roast my coffee. I'd say it usually tasted pretty good too. -When you did the macro shot of the bean it looked like some oil had soaked into the bean near the surface, but was locked in the bean structure, i.e. it didn't pour out when you cracked the bean. I'd be willing to bet that grinding also didn't release this oil(after all, coffee is full of oil) but the more efficient espresso process managed to extract that oil as well as the coffee oil as per normal.
I would be interested in knowing what happened to the oil as well; perhaps it would infuse it with caffeine or a coffee taste? Curious about the culinary potential.
I love how you got that first gulp in your mouth and then it goes dramatically silent right before you swallow your first bit really loud. That was super funny. You did such a good job on this video that I stayed and watched the whole video and you deserve this sub. Nice job, my man!
I’m sure that just like with regular frying the oil selection is key here, flavor and quality of oil varies, so you’d need to find a good combination. Olive, avocado, vegetable, butter, canola, etc. The right high quality oil paired with the right coffee could create quite a pleasant flavor. It might also help if you brew or roast with other flavorings, or if you filter the coffee repeatedly to remove a large amount of the oil (it might remove more of that greasy taste or mouthfeel while keeping that richness and robustness).
KFC supposedly uses just a bit of orange oil in their frying oil. You could do similar things here with coffee. Blend oils in a way that positively influence your flavor profiles.
The best kind of oils to use for deep fried coffee roasts are nut oils. Almond, sesame and peanut oils compliment the floral hints of coffee very well. But the ideal method would be to lightly spray the beans w. oil, then air fry rather than deep fry.
This reminds of the coffee in Malaysia and Singapore, where the coffee beans are roasted with margarine. The resulting coffee is surprisingly creamy without feeling greasy! 🥰
was about to say this. I think roasting with margarine is quite common in southeast Asia. ironically I found out about this through my cardiologist, when he saw a concerning number in my test result...
@@nchls1343 Ipoh White Coffee...Not that the coffee is white, just the term the Chinese immigrant in Malaysia used to distinguish from normal (black coffee)
I have never heard the word "good" used THAT conclusively with that many question marks attached before honestly by that description, james, that sounds like an absolutely blissful coffee for my palate
@@nrhodges2 Every friday night James snorts his saved up espresso pucks and turns into his chaotic alter ego, Hames. On monday he wakes up with no memory of this, and chuckles at the funny """edited""" Hames Joffman videos that appeared over the weekend.
This is the test of true satire, when the satirised becomes indistinguishable from the lampoon. I think of Hames Joffman like the Fast Show, a sketch show with just the punch lines.
Got an idea, glaze the beans in butter and airfry it, the butter will melt and absorb into the coffee and itll prevent the beans from dehydrating too much. Might give it a lighter texture and richer taste from only a light glazing butter than a vat of oil
I think you should revisit this with a couple of tweaks. 1) Finer mesh on your basket, so that you can actually stir the coffee around, get it consistently exposed to fresh, hot oil, and away from its neighbors. 2) Hotter oil. The hotter the oil, the less oily the thing you're frying will come out. This is of course to be balanced with, ya know, not burning the shit out of the coffee! I know how you like to experiment and play with recipes and variables. This seems like the exact kind of thing that may warrant a bit further investigation. Ya know, don't spend months on it testing every tiny little thing. But that pour-over coffee looked promising. Maybe with some adjustments here and there, it could even be a truly good cup of coffee? Either way, very entertaining video. I can't wait to see what Hames does with this, I just know it's going to be amazing.
Fry in ghee may be more of a butter coffee flavor, or lighter oils? More or less fry time too, but yeah a number of variables out of the initial attempt does sort of show potential.
While hotter oil helps for most deep-fry grease issues, the premise is that it's rapidly boiling the water in the fried product and those bubbles of vapor are keeping oil out. Coffee beans are a dried product and just don't have enough moisture to achieve this. This would also explain why we don't see other dried foods deep fried like spices or jerky.
Now I absolutely positively must try deep fried coffee. Also this needs multiple batches. That way you can experiment and perfect various techniques and try different colors. For one thing on one batch put some filter paper down under the coffee and spread it all out
My favorite part of a lot of recent vids is Jame's facial reactions in the moment. There is just something simple and joyous about seeing someone dive head first into an experiment and come out surprised/confused/happy all at the same time.
I wonder what it would be like if you fried it in a different oil, like peanut oil or coffee oil (assuming coffee oil is even something you can fry with).
Theoretically you could. The boiling point of coffee oil is roughly 313°C while peanut oil seems to be 300°C Dont know what the smoke point is for coffee oil, but you theoretically should be able to deep fry with it
James, you might have better luck getting less grease in the final beans if you fry at a higher temperature for a shorter time. Normally, the water inside of a food item flashing quickly to steam during the frying process creates enough outward pressure that oil has a hard time penetrating the deep fried food as long as the fry time is relatively short (so that the cooking process finishes before there's no more steam left to protect the food). Since coffee beans have a relatively low water content, your window to fry them before the water all evaporates is likely going to be quite short and the oil will need to be very hot in order to properly vaporize whatever water *is* there. If you want more details, your Modernist Cuisine books (Volume 2: Techniques and Equipment, I believe) have a whole chapter on the subject and the physics behind it. It might also be a topic that is worth reaching out to Chris Young & Grant Crilly about as solving this problem seems like it would be right up their alley. I do suspect that with a little bit of tinkering though, the leftover grease problem could be almost entirely eliminated... Perfect for many more experiments and videos!
Even if that worked you would probably have to first soak them inside of Vodka for a couple days because Vodka evaporates quickly when heated (More crispy beans so probably a better finished product)
@@qwizzler There is no fire risk frying batter with Vodka in it, so how would that differ? May I add incase you are one of the people who believes in something stupid: No ice doesn't make a fryer react it just cools down the oil and stops the frying process.
Could try double frying, too. With chicken, you fry to done, bump it up 100°F, then fry to crispy. The hotter temp drives the oil out of the breading and makes for far less greasy fried chicken. Lower temp to get the beans "done" then crank it up to dry them out.
Honestly, its because he has seen genuine coffee roasting machines, and the inside of them is either mesh, or looks like the inside of a washer (stainless drum, with holes) so i see why
Definitely do not leave the lid on when deep frying; as the product you are frying cooks, it will release steam and the water will condense on the lid and fall back into hot oil.
Indeed! It's only home deep fryers where the manual says to keep the lid on, and this is mainly to keep your kitchen clean, not for better frying. Professional deep fryers used in restaurants are never covered while frying.
Would love to see your take in other countries traditional style coffee. Here in Singapore our Nanyang coffee is roasted with butter and sugar, mostly using Robusta beans, and I believe there are other different styles out there. Would love to see a video of you trying those methods of roasting and the outcome!
very interesting! We do the same in the southern state of India (Kerala) too! Or rather, we used Ghee (clarified butter) a bit of sugar and a dash of Fenugreek.This was our traditional way of roasting robusta beans as well . Also traditional house hold coffee out here is always robusta.
I have that exact fryer. You didn't let it get up to temp before putting the beans in which affects the cooking process. Also a higher heat would've been suitable here.
I love how you are open to experimenting. I think the deep frying process dilutes the aromatics inside the coffee bean. Also the bean absorbed some of the frying oil so we get this confusing mix of aroma. V60 paper filter might work better since it absorb some of the frying oil.
You could definitely get lots of different flavors depending on the oil you use. you could also combine different ways of roasting or frying coffee. You can also wash the beans after frying to get more oil off, potentially.
I like that idea. Pouring some boiling water over beans in a metal screen mesh strainer, would wash that oil right off, especially in the deep part where it seemed to be gathered in his cross section. At the temperature of his fryer oil, not that much would have penetrated the bean. So any extra oil would be in those deep holes on the surface.
@@billparrish4385 boiling water would reduce the coffee's flavor, since you know, you use boiling water to make the coffee and throw out the grounds because you've leached all the flavor out.
@@youngeshmoney It would do so as grounds for sure, but as whole beans that have been deep fried, I'm hoping the balance between the flavor-leaching effect and the washing off of the extra fryer oil on the surface could be optimized. The water would destroy the crunchiness, necessary to getting a good grind. Maybe crisp them up again in an air fryer, then grind? Then again, deep frying may not be that viable an option, at least for espresso.
@@rogerunderhill4267 They don't mix, but boiling water would heat the oil, making it very thin, so that the force of the water could wash it off. Water and oil likewise don't mix in a salad dressing, yet shaking them together produces an emulsion containing both. So I believe it could get at least much of the excess oil off, but whether that would be enough to remove the bitter, fatty taste in his espresso is another question.
@@jameshoffmann James, any thoughts on a comparison between this "deep fried coffee" and Civet Coffee (Kopi Luwak)? The latter also has (in my opinion) low acidity and a smoothness to it. BTW, super glad I found your channel. You show 100% passion, have lots of great info, and no fluff (but plenty of funny moments). Cheers!
Hello, I’m a barista from Puerto Rico iv bin confectioning coffee for 7 years and I’m in love with the insight on the general coffee knowledge you offer on your channel… definitely coffee is the perfect medium for crazy chemistry science.
You know, if you're interested in heat transfer media, a lot of processes used to use hot sand as a medium. The idea is that the sand has a bulk to it so once it's hot it tends not to cool down as quickly compared to hot air for example (just like the oil) but wouldn't impart any grease to the final product.
If you mixed the beans with hot sand you’d likely dull your grinder much more quickly, no matter how carefully you tried to remove the sand. But maybe I misunderstood the method you’re proposing?
@@DSR216 How about hot salt - Similar idea to the salt, except that the leftover salt on the beans would be much easier on your grinder (as well as being able to dissolve in water)
Baking beans? if you could get some really small ceramic ones, but still large enough to remove reliably. They'd have the thermal mass if not the contact area.
there are street vendors in india/pakistan/bangladesh that serve hot sand or hot salt "fried" snacks exactly like the way you describe. there are videos of it here on youtube too.
Probably not a 1:1 comparison but this reminds me of local Malaysian coffee! afaik it's fried in a wok with sugar and margarine which gives it a very distinct mouthfeel and texture. Would love to see you explore kopi-o sometime!
Time for some science on thermal conductivity! the conductivity of air is approximately 26 mW/(m*K) at room temperature and approximately 40 at roasting temperatures. Fryer oil has a room temp conductivity of approximately 170 and a roasting temp conductivity of roughly 250. So the frying oil is transferring roughly 6x as much energy per second into the coffee as the air in the roaster. This probably explains the lack of cracking; heat is pumping into the beans so quickly that there's no time for pressure to build before all the moisture's gone. Here's where it can get interesting. Hydrogen gas has a conductivity of 186 at room temperature and 271 at roasting temperature, making it an even more effective heat transfer medium than fryer oil. In theory, you could place a coffee roaster in a vacuum chamber and replace all the air with hydrogen gas to achieve hyper-efficient heat transfer in a traditional roasting machine. However, heating elements and hydrogen gas don't play very nice together (See, The Hindenburg Disaster)
Regarding frying with the lid on: Check the directions for your particular fryer! I had one that specifically said to NOT put the lid on the machine when it was hot, because there was plastic in the lid that was not completely heat resistant.
That must have been designed by the guy who was having "his special day" at engineering school. Who in their right mind uses non heat resistant materials in an appliance whose sole purpose is to get hot?
@@jimnelsen2064 Yeah, that just sounds dangerous, best case you get some tasty microplastics melted directly into your food, worst case it causes a fire, not sure I'd trust an appliance like that, without opening it who knows if they cheaped somewhere else, like deciding they didn't need any over temperature protection cut-off in case the heater shorts out.
Totally agree. Some oils have a stronger flavor than others, say olive compared to sunflower... Also temperature can have influence in the way it roasts from the inside, but it seems very even at that temperature, but also it might be the way the oil does heat exchange (?) Lovely experiments can be done
I would be positively fascinated to see, if you were to optimize this method of preparing coffee, what raw beans and what presentation you think would most compliment the "roast". I also think it would be very interesting to try a few different oils and see how they affect the character of the cup.
Like somebody else mentioned I would definitely do this with peanut oil, it would complement the coffee much better than vegetable, and probably a higher oil temp.
A couple years back a friend of mine had vacationed in Viet nam. Knowing my passion for coffee, she brought back some coffee, supposedly look lowak, wok fried in butter (ghee most likely). It was buttery and surprisingly good. They roasted it in front of her so that is how they did it.

My favorite part of these tastings is that one terrible experience is not enough. Thanks James for verifying the disgust and letting us see your priceless expression multiple times in this video!
My uncle tried to get a patent for a home coffee oil separator like this 30 years ago when coffee culture got really popular in my country. It got rejected by the EU because coffee beans is a licensed and protected produce. If he wanted to make a patent he would need to cultivate his own strain of coffee beans. He was further ahead than recent pop culture though, he used physics to get the oil grease from the beans. He had device that separated the oil from the beans with water, heat and gravity, which is actually dangerous to keep near frying oil in a single machine. He also had a machine that let you brew coffee in vegetable oil and then separate the oil from the brew with condensation leaving only the extracted coffee essence. The secret trick was using a oil with a low freezing point. Then using heat and cold after separation, turning the oil into a semi solid gelatinous block even in room temperature.
Because james speaks in such a calm distinguished way, something inside me really wants him to take a sip of coffee one day and just say “Fu*k me thats good”🤣

There seems to be a trend in Japan in which coffee amateurs are roasting their coffee by using woks. Would be very interesting to see your trial and reactions. Thanks for your videos and sharing your knowledge. =)
Some teas like Long Jing are traditionally roasted in woks but the heat is so unequal that you have to be extremely fast and precise to make it properly. That is a Chinese tradition by the way, Japanese people are more known for steaming their teas in order to stop the enzymatic breakdown happening inside the leaves and buds, which is why their green teas mostly hit vegetal notes of seaweed, vegetables, fruit and sometimes raw seeds and nuts. I'm not sure how raw coffee would taste if it were to be steamed, but I'd mostly expect awful things.

If you’re looking to get them to puff up more, try the french fry method. Fry it at a lower temperature, then freeze them, then fry them again at a higher temperature for a shorter period of time.
I would love to see a bit more of this. Try to do a sous vide technique. Vacuum seal some coffee beans and deep fry. The fat won’t be a problem and you should be able to make an espresso. Also the beans should be more evenly cooked than traditional roasting as you could select internal temperature of the beans.

@Jon Beydler You're talking about the civet coffee from the philippines right? 😅😅
Nearest thing I can relate this to is a butter roast from French or Vietnamese coffee.
@Jon Beydler And it's so expensive it's ridiculous.
Some people also drink coffee from Elephants poop and they are more expensive from Luwak (Civet) coffee.
In malaysia and vietnam, we roast coffee with butter. Its gives a wonderful oily, savoury finish to the coffee and a nice lingering texture. There's a couple of youtube videos if you search for butter coffee , hainan coffee or Ipoh White Kopi (how its spelted in Malay). they also roast it with sugar to give it a richer flavour.
I was going to say, I would wonder if frying in ghee would be better and I would try a higher temperature at least once but wonder if staying below 350f is important for staving off potential maillard reactions.
@@PatrickKniesler The beans won't darken if you don't do it above 350 unless you do something to raise the pH of the beans.

I'm not a brewing expert by any means so I"m not sure how it would relate -but I've deep fried quite a bit, typically there is a plateau temperature to get above to avoid the food from just saturating with oil, different oils have different temperatures obviously, but if I were going to try this, contrary to what others have commented, I would try a hotter temp and probably use peanut oil. If you find the hotter temp cooks too fast, maybe pre-warm the beans in the oven or something. There is a point with deep frying where you can't just cook at a "lower temperature longer" you have to precook before you fry at that point.
I'm a chef and I was about to say the exact same thing. Peanut oil and a higher temp
I think another problem is that it seems that they're actually dehydrating the bean over actually cooking it, so I think you would have to do the opposite, high temp deep fry, then finish in the oven, I can't really solve that the goal is to make the bean more pourous by frying, while dehydrating
Frying is by nature for sealing up and keeping moisture in,
❤@@Misslayer99
I'd listen if I were doing it , sounds like a person with grill skill and deep fried the works already lol
@@phartferd5738 i feel like wayyy more trials need to be done cause yeah, what everyone who roasts coffee *expects* is for it to be dehydrated and porous, but it may not be a hard requirement

but i am not an expert and thus talking out of my nether regions
I saw a dude fried coffee with butter and chicory in a wok while I was walking around Saigon a few years back. He was kind enough to grind up a fresh batch to brew a small cup for me to try with some condensed milk. it was the best coffee that I have ever tasted.
You didn't taste the coffee, you tasted the experience and the condensed milk
If you're tasting the coffee you're doing it wrong, sour ass goat beans need to be hidden behind better flavors
@@vancodling4223that’s very rude I need to speak to your mother and give her a son she deserves.
The best condensed milk anyway...!!
@@vancodling4223 dude, you just don’t like coffee.
I think the oil temperature is a factor as well here. Typically for dried products that you want to "puff" (like puffed rice i.e.) you have to go way higher, at around 190°/200°C. With proper temperature, the oil penetrates way less in the product in general, and you might get a closer result in terms of cracking and size of the roasted bean
You know what that means... we need a part two!
But with coffee, wouldn't those temperatures begin burning the beans? Even water above 190/200 Fahrenheit cause damage to ground beans... outside of espresso, where you essentially burn it up.
There's some literature that contradicts this. They posit that high temperature oil makes bigger cavities in the food as it boils the water away more forcefully, which then fills with more oil than a low temperature fry does.
Need to roast in bacon drippings. Mmm... Now we are cooking with coffee
@@LordWhirlin You misunderstand what Andrea is saying. She meant 190-200 ºC, which is 374-392 ºF. High temperatures are required to roast (or in this case fry) the coffee beans. I'm not really familiar with the chemistry behind it, but what I'm guessing is that boiling water (~212 ºF) doesn't really burn the coffee, it just has a stronger extraction power, and therefore extracts more bitter compounds, causing the coffee to taste "burnt". That can be supported by the fact that cold brew coffee has a much more mild flavor and less complex, because the cold water can't extract some compounds present in coffee. The case of espresso actually adds more factors, not only the water can be over 212 ºF, but it also goes through the grounds under pressure, causing it to leach very hydrophobic compounds that don't usually get extracted due to their low solubility in water.
I was having a miserable morning and now I'm grinning from ear to ear. Thank you for suffering that espresso shot for all of us.

You mentioned a vegetable taste, you can purchase oil extracted from coffee beans. I'd be curious if that would be something you could use to fry the beans and see how that tastes
Woow imagine all that, with how other types of oil would affect the taste
@@Lavenshademaybe some of the sweeter oils like coconut or hazel nut maybe? I think I'd avoid olive oil to be honest though 🤢 lol
Try an Oelato@@carpenterstacey
That would essencetilly be re roasting them
i wonder can you get hazelnut oil.
I have a suspicion that what is happening in the filter brew is that with the unpressurized coffee draining down, the oils are able to float to the top of the slurry and sit on top of the bed rather than draining down with the water. It also explains why the resulting bed looks the way it does n
The oils are also absorbed by the filter itself, It would be interesting to see what happens if you were to use something like a Chemex filter that'll isolate a lot more of that end product.
Good point. Further to this, oil and water are immiscible, they repel each other. If the V60 filter was pre-rinsed with water, the water held by the filter would do a lot to resist the passing of the oil. You might get a very different cup if you didn't rinse the filter beforehand. In the espresso shot, this would likely not have mattered since there's an immense amount of pressure forcing everything through.
My thoughts exactly!
super correct insight !
If you used a quality creped filter like the cafec ones you would also catch a lot more of the oils in the paper.
I didn't know this man existed in the same universe as a deep fryer

@@Rob-nd1qb one in every crowd....
As a roaster/owner of a Roastery (Swamp Donkey Roastery), I appreciate your experiment, although I would suggest if you were to try it again, you go with a much higher oil temperature. While that may seem strange, I believe the beans spent too much time cooking in the oil, thus absorbing much more oil then they may have with a higher oil temperature. I would suggest an oil temp that would develop the bean in the 6 to 8 minute timeframe, I am sharing this thought as we roast in a Scandinavian Profile, very high heat in the beginning (neighborhood of 600 +/- degrees f w/a drop in the 400 +/- degrees f) of the roast, allowing the bean to go through first and second crack in about a 6 minute plus timeframe w/o tipping. The quicker development in the temps we utilize seems to reduce/eliminate undesirable acidity and bitterness while not caramelizing all the sugar in the bean for a much sweeter full flavored extraction, based on our experience and customer feedback.
Avocado oil has a smoke point around 500 F. That's pretty high end smoke point.
@@kayakMike1000 I'm unsure how the Avocado would affect the flavor, Refined Peanut oil is also a high smoke point oil except its max is 450f.
If I recall avocado oil also has a neutral flavor so it shouldn't affect the final flavor too much. It's even healthier than regular peanut oil.
Valuable information!!!!!
The weirdest way I've made coffee, according to a very old recipe, was to let the beans soak in cold water for a few hours and then to put the full beans in a French press and pour hot water just below boiling.
It ends up tasting like if coffee was tea.
LOL wtf
Lmao. Now, I want to make one 😂
Less bitter, lighter in color?
Sounds pretty good actually. But I do prefer tea over coffee
You also decaffeinated them
I'm sure the type of oil would make a huge difference in taste, but I actually want a part 2 trying to roast in different substances like butter/sugar/honey/vanilla/cream/etc.
What besides butter most them cant really be used to roast somthing suger is solid not sure boiling honey is going to cook anything and cream will melt snd vanila exstract is mostly a mix of alcahol and water its got a lower boiling point than water tho so it just boil it not roast it
I'd like to see how it goes with peanut oil

Same here, I am utterly fascinated.

The chemistry involved is intriguing 🧑🔬☕
If you ever decide to try it, use a French press. If you don't like it, you can use the french press to make tea instead! It's an old invention, but it's waaay smoother than the burnt taste that drip coffee or teabags make.

Deep fried coffee, or fried coffee, is pretty common in the preparation of kopi (southeastasian singapore/malaysian style coffees). It's usually fried in a wok, then filtered through a coffee "sock" and then poured over in glass mugs. There's variations with different coffee strengths and ratios of coffee : water and also using evaporated milk or condensed milk as sweeteners (similar to vietnamese coffee)
That seems like a way better option then a deep fryer, interesting to know! Thanks!
Actually the process of frying coffee in a wok resembles more of roast than fried, as in frying/deep frying often use oil as the main heating agent.

The initial reaction is probably one of James' best. Now I'm wondering if he's ever tried roasting coffee in a popcorn popper.
Probably hasn't tried it but is likely aware of it as it's the same principle as the air drying process he described.

C8 MCT coconut oil, if you're going to do a bullet proof coffee. For myself, I'll just stick with air roasted coffee. However, this does get me thinking about other methods of roasting coffee. IR lamps perhaps?
One tip to stop the beans falling through the mesh. Cover the beans in batter before you fry them, it bulks them up a bit.
now thats a real american coffee
And grind like that or get a toothbrush to remove it?
Perhaps for a batter you could use finely ground green beans stirred into a water and cornstarch gravy after it had cooled.

@@laZOETje Donuts and coffee. If only those taste good together.... WAIT!
Honestly, if you've got something you've described as "good" when it's your first shot at trying it with equipment that's not designed for it, you might have a winner on your hands. Remember, your technique is only going to get better, and you've got variables you can play with in terms of frying times. An even roast through the whole bean has to be a fantastic starting point.
I would suggest that the reason the filter coffee works is because any remaining oil is floating to the top of the water as you apply it and is then just sitting on top of the bed at the end instead of making its way through the filter, so you're unwittingly filtering it in two different ways at the same time. I don't think there's a way to replicate this effect by espresso, and that's fine.
Yeah, nobody makes a good batch at first shot(at classic roaster). Also, his fried coffee didn´t rest at all.
I do think there's most definitely room to explore this further, but as I don't own a deep fat frier I cannot partake!
Specifically regarding the espresso, I wonder if stepping back in time a little might help with the observed acidity and harshness: Dosing high and pulling short, like we did back in the 90s to make some of those harsher espresso blends more pleasing with (fatty) milk serves.
Most interesting to me was the consistency of the fry: Whilst bean to bean was clearly not very consistent at all in this small frier, I wonder if (as it often does with roasting) scaling up would remedy this to some degree: Anyone fancy chucking half a kilo in their kitchen's Thor? :D
James guessed at the frying temperature. The lack of cracking makes me very curious if his oil was hot enough. He acknowledged that his grate was too coarse and let a lot of beans fall through. So many ways this could be "dialed in." In fairness, I've never roasted coffee. Give me a coffee roaster, of any type or brand, and I suspect my first batch would be horrible. Maybe fried beans have no place in an espresso machine, but I think it would be very interesting to experiment and dial in for pourover. If the first attempt was "not bad" that suggests good, if not great, is achievable.
Yep, and there is no pressure to squeeze that oil through paper filter too.
Great video. Your reaction to the filter brew was brilliant. 😂 The struggle to try to come to terms with your creation brought a smile to my face. The espresso reaction brought tears to my eyes.

Cannot wait for part 2 where James breaks down the pros and cons of various frying oils on different brews.
The initial observations in this are super interesting to think about in comparision to experiment of deep-fried vs air fried food or how to layer fats in a sauce without over doing it so it feels greasy. I wonder if there is a sweet spot that could be achieved through convection roasting with a small amount of oil on the beans for the espresso pull to get that same rounded off flavor that was good in the filtered coffee without the oily feel.

a few recommendations from my roommates and I:
from my own experience as a home cook: i’ve filtered/clarified oil on my own with a variety of meshes and filters, and i know coffee moves through a coffee filter significantly faster than oil. your pour over cup may have been less oily because of the paper filter
from roommate 1’s experience as a fry cook: even if you have your frier at a high temp, if the item you’re frying doesn’t sizzle upon impact, you need to increase the fry temp. the reason why fried food isn’t chock-full of oil is because of the force of the water evaporating and pushing back against the oil. in his words, “even if you increase the tempurature after putting it in, if it’s been frying without sizzling it’s too late.” his recommendation was to increase the initial fry temp and then decrease it to your preferred tempurature after a little bit.
from roommate 2’s experience as a science nerd: there are substances you can use to extract the oil from things, so maybe you should do that to your espresso either before brewing or before drinking.
i’m not clear on how this last recommendation works or what you’d have to look for because i don’t understand chemistry really.
Fascinating thank you
For the last one you could use something like a couple DCM or ethyl acetate washes, the problem is that a lot of the flavours in the coffee aren't particularly polar either, so you are going to extract them as well. For example caffeine is also DCM and ethyl acetate soluble so some (many cheap/bad) decaffs use those washes for their process. In other words you're gonna end up with a much more flat decaff-like tasting end product.
If what you are trying to fry, has no "water", then its not going to sizzle much, if at all. If he pre-wet the beans, then the beans would have that mini "steam-cook" effect in the oil, in the same way that a French Fry would cook in the fryer.
@@johndough8115 Water is one of the "stickiest" materials. In a vacuum, you could be down to 0.0001 atmospheres and there will sstill be water. In other words, there will always be a sizzle.
Wouldn’t do that last one unless you’re prepared to lose a lot more than oil and maybe have solvent residue in your coffee
The fact that it turned out quite nice first try, on some random settings (given that there's little known about how to correctly deep fry one's coffee beans) makes me think that with a bit of experimentation this could be a legit method.
Maillard is the way to go. Frying makes everything taste good
Would be interesting to see air frying if that's more similar to a traditional roaster and something people are likely to have around
Air fryers are absolutely capable of roasting but you need the beans to be constantly moving which I’ve never seen on common air fryers
Edit: I stand corrected. Some come with rotisserie baskets which might allow you to keep the beans moving enough where they can roast evenly.
If you have one it's worth a shot but if you don't want to spend a lot of money to try roasting your own you can try the cast iron method or check out your nearest thrift shop for a popcorn air popper. I used one of these and got 50g coffee done within about 7 minutes and they tasted pretty good.
You can do it just in your oven and it will be delicious if you do it slow enough.

Let's get this onto a tray.
In Singapore we have nanyang style coffee where the beans are roasted with butter and sugar. But it’s usually roasted dark and brewed using suspension and a cloth filter. I believe this method was developed to work with the coffee grown in Southeast Asia. Somehow grease and coffee works lol
Traditionally Ethiopian coffee is served with spiced clarified butter. It's wonderful!
Roasting with butter/margarine and sugar is done to improve the taste of the more bitter robusta beans that are used in kopi and other SEA coffee. (International specialty coffee basically never uses robusta since robusta can't match the taste of arabica beans, which are a lot more expensive.) That said, roasting with a fat is very different from deep-frying with it - the medium of conduction is air vs liquid fat.
Ooo I miss the coffee sock! Apparently they brew coffee in coffee socks in Colombia too!
I was looking for this before commenting about it myself!
I've heard about people doing it the opposite way, too, using butter to fry up coffee beans super lightly. I dunno if this is a misinterpretation of a more traditional style or not but I've heard it referred to as "white coffee".
My great-grandpa had his own recipe involving the use of butter, sugar, and the previous day’s roast (although I suspect the latter is just his way of cutting corners).
This one of the funniest videos I have seen in a while. I love how professional he is while dealing with something this ridiculous and how genuinely surprised he gets when it actually turns out good. The fan part was my favorite 🤣
I love your genuine interest. You are curious and you can not help but to satisfy your curiosity...fantastic and Thank You!!!
This reminds me a lot of “Nonya coffee” in Singapore & Malaysia!
They roast the beans in margarine before grinding & brewing it in a large “sock” (very similar extraction style to filter). It’s drank widely with a bit of condensed milk or sugar - but many people also have it black with with some water.
I’d describe it similarly to James did here. It’s coffee but without the complex & interesting bits, and the flavour is much rounder, softer, & less acidic! Crazy stuff
Thinking of Ipoh white coffee as well, roasted in palm oil.
I doubt that it's margarine. Probably a vegetable oil.
@@Chris_Garman you can make margarine out of veggie fats
@@thepenguin9 true, both will kill you tho
@@thepenguin9 Yeah, but you want the ones with expeller-pressed oils like found in organic margarine (Earth Balance, Smart Balance), non hydrogenated ones like industrially-processed margarines (Country Crock etc).
I think the reason why the "pour over" one tasted better was that the deep fryer oil had time to rise to the top and was left there due to density differences. While the rest of the coffee's goodness drained down. On the other hand, the espresso machine uses pressure to push down all the liquid contents and also pushes most of the deep fryer oil mixing with the shot. In that process, it then overpowered the coffee, making it taste not very good.
Have you heard of the Save Soil movement before?🧘♀️🌎🌍🌏
Good point, that would explain why the filter looked so full of muck too, it was all the fats stuck to the paper and grounds.
@@xxshevilxx that’s right
I love how he tastes the first coffee, and we're treated to 15 whole seconds (including a jump cut, so it was probably lonter IRL!) of James just being a physical incarnation of the "visible confusion" meme.
and then the deep fried espresso bean
I've never watched coffee related content, and I've never come across this channel.
That being said... This video had me thoroughly entertained.
When people deep fried the food, we normally deep fried it twice, the first time in a lower temp say 160-165c to cook the food and the second time in a higher temp say 175-185c to push the oil out from the food. If you skip the second step, the food will be very oily. And this is also what happened in the video.
Yeah, he thinks he knows what he’s talking about lol
considering how you could taste the vegetable-ness, makes me wonder how other types of oils might pair with certain types of beans, like ghee (type of clarified butter that's cheap to make) might be an interesting combination, and the ghee itself will have an interesting flavor too lol
Or coconut oil or avocado oil!
that vegetableness may come from some raw part of beans from inside too. cooking with oil will transfer heat faster and everywhere, when you roast it some of it may be raw inside.
Mmmm. Ghee or lard could be amazing. Maybe coconut oil . . .
Ghee is cheap to make? As if butter doesn’t cost $6/LB
@@tjprosper7704 butter here is $3.95/lb. (at Aldi). Our Aldi sells ghee, but I don’t know how much it is.
This is a shot in the dark, but I think the process of making filter coffee also does a good job of filtering out the grease. It's going to float on the top during most of the brew and get trapped by the bed during the drawdown. The paper might help as well. With espresso you're forcing all the grease the other side, you don't get this gravity aided density separation.
Good pun
I think the same too. With espresso you kinda brew the coffe with higher temperature (steam) along with higher pressure. The heat makes the oil kinda melted/less viscous and pressurized to pass through the filter. That didn't happened with manual brew because the melted fat will most likely stuck to the paper and not enough pressure to push it pass thru that paper.
Excellent point.
And that probably happens with roasted coffee's own oils as well.
oh no, that totally makes sense
like a combination of gravity and the filtering action of the bulk matter of the coffee itself keeping oil at bay
I love the face when he drinks it. Just “I hate the fact I don’t hate this”
On reflection, I’m thinking the oil in the V60 probably floated to the top of the bloom and were “filtered” by the grounds so that it remained in the filter. With the espresso, all those oils were pushed straight through into your shot. As always, thanks for taking one for the team so we don’t have to.
Oil is less dense than water, that's why it didn't clog the filter.
@@goncalovazpinto6261 hot water being poured through it could easily cause enough turbulence to make some stick to the filter. It takes a bit for oil to fully form a separate layer when it's mixed up
@@mrastleysghost I don't think so. The first thing that happens is that the filter gets wet. Once the filter is wet it will repell water and only let water soluble stuff through. When you start poring water, you specifically avoid causing turbulence, that's part of the V60 technique.
Also, any amount of oil, however smal, will rise to the top and form a film. Whem the film is very thin it looks like waves of blue/yellow lines on the surface.
@@goncalovazpinto6261 What are you on? Passage across an unstirred water layer is rate limiting, but not an impenetrable wall. Pouring water will cause turbulence, V60 is no exception. Oil will rise to the top, given time and low turbulence. Before that, it's suspended and subject to all sorts of motions.
You express yourself in absolutes, whilst chemistry is much more nuanced.
@@Karius7 And yet, the filter coffee was "good" and the expresso was "oily".
Chemistry is science, i. e. building predictive models.
V60 is an extremely gentle pour, also the water has to go through a mostly undisturbed bed of coffee grounds before it reaches the filter.
I don't know if it was the case this time, but often you wash the filter before the coffee even goes in.
If I wasn't nuanced enough for you it was for the sake of conciseness.
Some oil will pass, not enough to change the flavor significantly: It is also a slower process than the expresso, so more time for the coffee grounds to interact with the hot water.
Probably the bloom also has some effect on the separation of the oil from the coffee (no bloom in expresso). Also the crema in the expresso might be carrying most of the oil.
There.
I used "some" "enough" "significantly" "more" "probably" "might" and "most".
Nuanced enough? 😁
If I can say “I don’t know how to deal with that emotionally” about a cup of coffee, well, that is a cup worth brewing.
Chemical engineer and former DIY coffee roaster here, just a couple of notes.
-Caffeine is technically soluble in oil. I'd be curious what the caffeine content of that oil was afterwards, especially if you did this regularly :D
-The beans had a very wide distribution of roast levels, all the way from City(minus) to almost French. I ended up with something similar back when I was using a cheap popcorn popper to roast my coffee. I'd say it usually tasted pretty good too.
-When you did the macro shot of the bean it looked like some oil had soaked into the bean near the surface, but was locked in the bean structure, i.e. it didn't pour out when you cracked the bean. I'd be willing to bet that grinding also didn't release this oil(after all, coffee is full of oil) but the more efficient espresso process managed to extract that oil as well as the coffee oil as per normal.
Good assessment, that's probably what happened!
Can you produce evidence my boi or cheap talk?
@M60gunner1971 🙄 It's a logical evaluation. You have an alternate theory?
@@mrfly8133 bean demons
I would be interested in knowing what happened to the oil as well; perhaps it would infuse it with caffeine or a coffee taste? Curious about the culinary potential.
I love how you got that first gulp in your mouth and then it goes dramatically silent right before you swallow your first bit really loud. That was super funny. You did such a good job on this video that I stayed and watched the whole video and you deserve this sub. Nice job, my man!
I’m sure that just like with regular frying the oil selection is key here, flavor and quality of oil varies, so you’d need to find a good combination. Olive, avocado, vegetable, butter, canola, etc. The right high quality oil paired with the right coffee could create quite a pleasant flavor. It might also help if you brew or roast with other flavorings, or if you filter the coffee repeatedly to remove a large amount of the oil (it might remove more of that greasy taste or mouthfeel while keeping that richness and robustness).
I was totally expecting him to to about oil choice. I was thinking as neutral as possible, but I like your flavour combination idea!
i bet coconut would be good
yeah, like peanut oil would probably be quite good here as the nutiness paired with coffee would accentuate the flavor rather than add weird notes.
KFC supposedly uses just a bit of orange oil in their frying oil. You could do similar things here with coffee. Blend oils in a way that positively influence your flavor profiles.
The best kind of oils to use for deep fried coffee roasts are nut oils. Almond, sesame and peanut oils compliment the floral hints of coffee very well. But the ideal method would be to lightly spray the beans w. oil, then air fry rather than deep fry.
This reminds of the coffee in Malaysia and Singapore, where the coffee beans are roasted with margarine. The resulting coffee is surprisingly creamy without feeling greasy! 🥰
was about to say this. I think roasting with margarine is quite common in southeast Asia. ironically I found out about this through my cardiologist, when he saw a concerning number in my test result...

I think low temperature and good heat transfer is what created that flavour profile. Shame about the infused oil though. It has given me an idea.

Got an idea, glaze the beans in butter and airfry it, the butter will melt and absorb into the coffee and itll prevent the beans from dehydrating too much. Might give it a lighter texture and richer taste from only a light glazing butter than a vat of oil
I think you should revisit this with a couple of tweaks.
1) Finer mesh on your basket, so that you can actually stir the coffee around, get it consistently exposed to fresh, hot oil, and away from its neighbors.
2) Hotter oil. The hotter the oil, the less oily the thing you're frying will come out. This is of course to be balanced with, ya know, not burning the shit out of the coffee!
I know how you like to experiment and play with recipes and variables. This seems like the exact kind of thing that may warrant a bit further investigation. Ya know, don't spend months on it testing every tiny little thing. But that pour-over coffee looked promising. Maybe with some adjustments here and there, it could even be a truly good cup of coffee?
Either way, very entertaining video. I can't wait to see what Hames does with this, I just know it's going to be amazing.
Fry in ghee may be more of a butter coffee flavor, or lighter oils? More or less fry time too, but yeah a number of variables out of the initial attempt does sort of show potential.
Might be able to start with much hotter oil to kind of sear the outside to keep the oil out and then drop the temp for the actual roast?
While hotter oil helps for most deep-fry grease issues, the premise is that it's rapidly boiling the water in the fried product and those bubbles of vapor are keeping oil out. Coffee beans are a dried product and just don't have enough moisture to achieve this. This would also explain why we don't see other dried foods deep fried like spices or jerky.
also maybe hotter, but do not cool it down so the carry on heat will roast it internalky for a bit

Now I absolutely positively must try deep fried coffee. Also this needs multiple batches. That way you can experiment and perfect various techniques and try different colors.
For one thing on one batch put some filter paper down under the coffee and spread it all out

I did. I knew I’d hear that eventually. However, I thought I’d be hearing it from an American first.
I wonder what it would be like if you fried it in a different oil, like peanut oil or coffee oil (assuming coffee oil is even something you can fry with).
Could one use lard perhaps? Or bacon fat?
wondering the same this but for butter or something as well
Cocoanut oil will sustain the buzz lol,.
ghee
Theoretically you could. The boiling point of coffee oil is roughly 313°C while peanut oil seems to be 300°C
Dont know what the smoke point is for coffee oil, but you theoretically should be able to deep fry with it
i've been roasting my own beans using a hit air popcorn popper, it works well, by the way; i'm going to try this too, life is for experiences!
James, you might have better luck getting less grease in the final beans if you fry at a higher temperature for a shorter time. Normally, the water inside of a food item flashing quickly to steam during the frying process creates enough outward pressure that oil has a hard time penetrating the deep fried food as long as the fry time is relatively short (so that the cooking process finishes before there's no more steam left to protect the food). Since coffee beans have a relatively low water content, your window to fry them before the water all evaporates is likely going to be quite short and the oil will need to be very hot in order to properly vaporize whatever water *is* there. If you want more details, your Modernist Cuisine books (Volume 2: Techniques and Equipment, I believe) have a whole chapter on the subject and the physics behind it. It might also be a topic that is worth reaching out to Chris Young & Grant Crilly about as solving this problem seems like it would be right up their alley. I do suspect that with a little bit of tinkering though, the leftover grease problem could be almost entirely eliminated... Perfect for many more experiments and videos!
Sounds like more frying required
Even if that worked you would probably have to first soak them inside of Vodka for a couple days because Vodka evaporates quickly when heated
(More crispy beans so probably a better finished product)
@@leagueaddict8357 no fire risk there.
@@qwizzler There is no fire risk frying batter with Vodka in it, so how would that differ?
May I add incase you are one of the people who believes in something stupid: No ice doesn't make a fryer react it just cools down the oil and stops the frying process.
Could try double frying, too. With chicken, you fry to done, bump it up 100°F, then fry to crispy. The hotter temp drives the oil out of the breading and makes for far less greasy fried chicken.
Lower temp to get the beans "done" then crank it up to dry them out.
I love that he compared a coffee roasting machine to a washing machine and then described a dryer 🤣
Lol a dryer is a machine used in the washing process.... 😅
@randomaccount2448 correct. However, in my house, the act of washing the clothes is not complete until they are put away
bro i think he was describing an air fryer
@@tribalismblindsthembutnoty124which is why you're the only one who does laundry
Honestly, its because he has seen genuine coffee roasting machines, and the inside of them is either mesh, or looks like the inside of a washer (stainless drum, with holes) so i see why
Definitely do not leave the lid on when deep frying; as the product you are frying cooks, it will release steam and the water will condense on the lid and fall back into hot oil.
Yeah who does that, the covers there to stop things falling in hot oil when it's not in ise
It’s actually ok with a lid like that it’s basically half mesh at the top
Yeah, the designers have thought of that…the steam gets out.
Indeed! It's only home deep fryers where the manual says to keep the lid on, and this is mainly to keep your kitchen clean, not for better frying. Professional deep fryers used in restaurants are never covered while frying.
I think that the type of oil may make a difference. Try coconut oil. I would add a touch of coconut oil and then air fry it.
I came for the title, but I stayed for your reactions. Thank you for putting yourself through this.
You gotta watch some of his videos where he drinks like 80 year old coffee.
Would love to see your take in other countries traditional style coffee. Here in Singapore our Nanyang coffee is roasted with butter and sugar, mostly using Robusta beans, and I believe there are other different styles out there. Would love to see a video of you trying those methods of roasting and the outcome!
very interesting! We do the same in the southern state of India (Kerala) too! Or rather, we used Ghee (clarified butter) a bit of sugar and a dash of Fenugreek.This was our traditional way of roasting robusta beans as well . Also traditional house hold coffee out here is always robusta.
Yeah this would be interesting - I wasn't aware of this method!
I have that exact fryer. You didn't let it get up to temp before putting the beans in which affects the cooking process. Also a higher heat would've been suitable here.
get back to us once you figure out exactly the right temp 😆
I love how you are open to experimenting. I think the deep frying process dilutes the aromatics inside the coffee bean. Also the bean absorbed some of the frying oil so we get this confusing mix of aroma. V60 paper filter might work better since it absorb some of the frying oil.
You could definitely get lots of different flavors depending on the oil you use. you could also combine different ways of roasting or frying coffee. You can also wash the beans after frying to get more oil off, potentially.
I like that idea. Pouring some boiling water over beans in a metal screen mesh strainer, would wash that oil right off, especially in the deep part where it seemed to be gathered in his cross section. At the temperature of his fryer oil, not that much would have penetrated the bean. So any extra oil would be in those deep holes on the surface.
@@billparrish4385 boiling water would reduce the coffee's flavor, since you know, you use boiling water to make the coffee and throw out the grounds because you've leached all the flavor out.
@@youngeshmoney It would do so as grounds for sure, but as whole beans that have been deep fried, I'm hoping the balance between the flavor-leaching effect and the washing off of the extra fryer oil on the surface could be optimized. The water would destroy the crunchiness, necessary to getting a good grind. Maybe crisp them up again in an air fryer, then grind?
Then again, deep frying may not be that viable an option, at least for espresso.
water can’t wash oil off. they don’t mix. That’s why James used a paper towel.
@@rogerunderhill4267 They don't mix, but boiling water would heat the oil, making it very thin, so that the force of the water could wash it off. Water and oil likewise don't mix in a salad dressing, yet shaking them together produces an emulsion containing both. So I believe it could get at least much of the excess oil off, but whether that would be enough to remove the bitter, fatty taste in his espresso is another question.
This is legitimately fascinating; how many people expected this to be awful?
I definitely did.

Hello, I’m a barista from Puerto Rico iv bin confectioning coffee for 7 years and I’m in love with the insight on the general coffee knowledge you offer on your channel… definitely coffee is the perfect medium for crazy chemistry science.
Idk why I watch this, I don't even like coffee. But your personality and presentation are top notch.
You know, if you're interested in heat transfer media, a lot of processes used to use hot sand as a medium. The idea is that the sand has a bulk to it so once it's hot it tends not to cool down as quickly compared to hot air for example (just like the oil) but wouldn't impart any grease to the final product.
If you mixed the beans with hot sand you’d likely dull your grinder much more quickly, no matter how carefully you tried to remove the sand. But maybe I misunderstood the method you’re proposing?
@@DSR216 i imagine that's correct...
@@DSR216 How about hot salt - Similar idea to the salt, except that the leftover salt on the beans would be much easier on your grinder (as well as being able to dissolve in water)
Baking beans? if you could get some really small ceramic ones, but still large enough to remove reliably. They'd have the thermal mass if not the contact area.
there are street vendors in india/pakistan/bangladesh that serve hot sand or hot salt "fried" snacks exactly like the way you describe. there are videos of it here on youtube too.
I’m not even a coffee guy and I’m digging the need to boldly go where no man has gone before. Kudos. You get a sub.
Probably not a 1:1 comparison but this reminds me of local Malaysian coffee! afaik it's fried in a wok with sugar and margarine which gives it a very distinct mouthfeel and texture. Would love to see you explore kopi-o sometime!
Time for some science on thermal conductivity! the conductivity of air is approximately 26 mW/(m*K) at room temperature and approximately 40 at roasting temperatures. Fryer oil has a room temp conductivity of approximately 170 and a roasting temp conductivity of roughly 250. So the frying oil is transferring roughly 6x as much energy per second into the coffee as the air in the roaster. This probably explains the lack of cracking; heat is pumping into the beans so quickly that there's no time for pressure to build before all the moisture's gone.
Here's where it can get interesting. Hydrogen gas has a conductivity of 186 at room temperature and 271 at roasting temperature, making it an even more effective heat transfer medium than fryer oil. In theory, you could place a coffee roaster in a vacuum chamber and replace all the air with hydrogen gas to achieve hyper-efficient heat transfer in a traditional roasting machine. However, heating elements and hydrogen gas don't play very nice together (See, The Hindenburg Disaster)
Regarding frying with the lid on: Check the directions for your particular fryer!
I had one that specifically said to NOT put the lid on the machine when it was hot, because there was plastic in the lid that was not completely heat resistant.
That must have been designed by the guy who was having "his special day" at engineering school. Who in their right mind uses non heat resistant materials in an appliance whose sole purpose is to get hot?
@@jimnelsen2064 Yeah, that just sounds dangerous, best case you get some tasty microplastics melted directly into your food, worst case it causes a fire, not sure I'd trust an appliance like that, without opening it who knows if they cheaped somewhere else, like deciding they didn't need any over temperature protection cut-off in case the heater shorts out.

Totally agree. Some oils have a stronger flavor than others, say olive compared to sunflower...

My uncle tried to get a patent for a home coffee oil separator like this 30 years ago when coffee culture got really popular in my country. It got rejected by the EU because coffee beans is a licensed and protected produce. If he wanted to make a patent he would need to cultivate his own strain of coffee beans.
He was further ahead than recent pop culture though, he used physics to get the oil grease from the beans. He had device that separated the oil from the beans with water, heat and gravity, which is actually dangerous to keep near frying oil in a single machine. He also had a machine that let you brew coffee in vegetable oil and then separate the oil from the brew with condensation leaving only the extracted coffee essence. The secret trick was using a oil with a low freezing point. Then using heat and cold after separation, turning the oil into a semi solid gelatinous block even in room temperature.

Some teas like Long Jing are traditionally roasted in woks but the heat is so unequal that you have to be extremely fast and precise to make it properly. That is a Chinese tradition by the way, Japanese people are more known for steaming their teas in order to stop the enzymatic breakdown happening inside the leaves and buds, which is why their green teas mostly hit vegetal notes of seaweed, vegetables, fruit and sometimes raw seeds and nuts. I'm not sure how raw coffee would taste if it were to be steamed, but I'd mostly expect awful things.

Also the beans should be more evenly cooked than traditional roasting as you could select internal temperature of the beans.
That’s putting plastic in hot fat. There is absolutely no way that this can go right.
James reluctantly saying something is good is my favorite expression
I love watching him try and talk himself out of this actually being as good as it is
