You are doing it wrong ;P. Greetings from Poland
Hi Adam, as you probably can see below, you've happened to cover a serious polish topic, fermented cucumbers is basically grandmas candy here xd But it also happens for a reason, there is no comparison between bought jar and the traditional one made home for the 100th time from stuff from your own garden. If you'd like to try good ol' "kiszoniak" please dm me, my granny would be more than happy to send you a jar. Do uszłyszenia!
Is salt free lacto fermentation possible at home. This needs to be found out
BOOBA
Idk if fermented food is actually beneficial if the bacteria just die in the gut acid
Here in Poland we're doing it all year long. Grandma just weighs down the solid stuff with a tiny plate that fits inside the jar (we've got large jars), then another plate on top to cover the opening and I've never seen a spoiled sour pickle on my life. Oh and we also add whole horseradish root and mustard seeds to them, sometimes a tiny bit of chilli. These spices really elevate the taste, especially horseradish (a thumb size or two for like a pound of cucumbers is enough)
It's important to mention Poland uses a different dill. Not a fresh, tiny plant. We use a fully matured dried dill stem along with the seed head.
A day old pickle is the best. Fully fermented ones are best for soup, or on a bread with lard. This is the way.
@@monikadraws this exactly about the dill, it basically tastes a little bit more like fennel seeds or even anise if you let the dill to bloom and use the entire flower/seed heads.
Mustard seeds are also great pickled on their own. They're like little spiced vegetal caviar. Make for a nice topping on other stuff.
i like whole peppercorns, dill and garlic, comes out wicked awesome.
did lil yachty bring the wock?
I'm polish - the "half-sours" (małosolne), and lactofermented cucumber pickles (kiszone) are a normal, everyday thing for us. My parents have always a pot of "kiszone ogórki" fermenting in the kitchen. And on Christmas we make a soup from lactofermented red beets. Sauerkraut is also very common, as it is in Germany.
Baltic neighbour here, lactofermented is such a mouthful in english compared to my native tongue haha, they're really common here too. I always preferred pickled pickles though. Not sure about the half sours... I don't think we have a special name for it, think we just say freshly/lightly lactofermented pickle?
Can you buy it in Biedronka or something like that? or when would you go? I'm from Czech, live on the border though. sometimes shop in Poland.
@@djVania08 yup, you should be able to buy them at Biedronka or any other store for that matter. They can also come in plastic bags instead of jars and if you go to a local market you can sometimes buy them straight from a big barrel.
@@djVania08 Yes, Biedronka sells małosolne in a small plastic bucket and Lidl has them in a bag.
@@superbuzia malosolne it is :D
I don't know.
Very cool, fatfish
Very honest.
Thanks man
I do.
Why?
In Poland (and other Eastern/Central European countries) we have ogórki małosolne which is virtually the same thing as half-sour pickles, it translates to low-salt cucumbers though. Super fresh and yummy stuff, the taste of spring and summer!
im not a big fan of your profile picture
Exactly! Sometimes people take them out after two or three days and eat them. Even when I do a fully finished version, it takes me a week to one and a half (when it is warm in summer) and Adam has to wait for weeks? Maybe for winter, but when it is warm it goes very quickly.
That makes a looot of sense since there was a huge influx of polish Jews to New York
Ogórki małosolne
dokładnie tak :)
You just solved an old childhood mystery for me! My family comes from Eastern Europe, mostly Belarus and Russia. I remember we would always have pickles as a side for lunch and dinner that my mom and babushka would make. In Russian, we called them "low salt" or малосольные pickles. After my family moved to Canada and tried local pickles, I noticed that the local American variety tasted quite different. Our low salt ones were not as vinegary and tasted kinda fizzy, and I always wondered why that was. When you said that not having enough salt to kill all the bacteria causes lactofermentation, that's when the last piece of the puzzle finally clicked into place.
Yeah, the fizzy part means the carbonation is still present, if you ferment fully and store fermented veg for around a week the carbonation will usually go flat and it'll also be about as sour as it will get. Kind of like how beer is carbonated but wine is not. I usually press out the carbonation when I ferment as it creates gas pockets that dry and discolor the veg.
So cool thanks for your story!
@@PerfectDeath4 I personally love fizzy lacto-fermented pickles
The only difference between low-salt ones and "normal" eastern-european pickles is fermentation time, in both cases you are using around 3% of salt, but in case of low-salt you stop the fermenatation after just few days, thats why they are fizzy and less salty. If you keep them longer and wait for bacteria to naturally finish fermentation, you will end up with saltier and more sour product but that pickles can be canned/pasterized and keep safely stored for months or even years (we still have few jars from 2020 season in our cellar and those are fine). Also at least here in Poland in traditional recepies we do not use any vinegar, we rely solely on lactic acid.
@@-TheBugLord I desperately want to try a fizzy pickle lmao that sounds so good and satisfying idk why, maybe it's because I love dill pickles but also Kefir so the idea of fizzy sour things entices me
I'm Indian, and pickles (Achaar) are a staple with almost every meal. There's too many types, ones in vinegar & brine, some that are spicy in a chilli paste base, oily varieties, sweet sour spicy jams... and there's tons of varieties, lemon, mango, tamrind, carrots, cucumber, chilli, garlic, raddish, beets, all seasoned and spiced for a very flavorful condiment to have with rice & a side dish. :) I recommend trying them if you run into them in the international aisle.
pickles in India are not generally brime fermented though, in India we basically use oil and spices to ferment the pickles which is a bit different :)
As several people mentioned below 'half sours' are pretty popular in Poland. They used to be avaiable seasonally, i think now you can get them all year. They used to be sold straight from a barrel.
All piekles are common sidedishes to vodka and are pretty omnipresent.
Wait! I'm supposed to have sidedishes with my vodka?! :)
@@Chris-ut6eq Makes it more fun :)
@@Chris-ut6eq I don't. I like the taste. But it's popular and I think it was even compulsory in bars during communism times (you couldnt order just vodka, so people ordered the cheapest sidedish there was, which was a pickled cucumber)
@@Chris-ut6eq a pickle with a drink keeps ya hydrated and has electrolytes. It was a staple of my liquor days, I'd either do a few shots and munch a pickle and keep some water nearby for legit hydration or I'd do a pickle back chaser with the brine.
Usually allows for a heavy night of drinking with minimal hangover effects, tastes good too. Granted it's not a cure all, but does work quite well when done in the right amounts.
Water intake plays a bigger part I'd say, but the salts do also help you retain water.
@@jeanvonestling7408 that’s interesting
Another info to add to the Polish love for fermented cucumbers: the brine is drinkable! It is super tasty, it is a natural isotonic, it is packed with great stuff (vitamin C, and all these great lacto bacteria that is good for your gut), and it is one of the best things to drink when you are hungover.
Makes for a good soup base too!
Its also really good for helping with muscle cramps.
fermented cabbage brine is delicious too
I made a drink based on the brine - 2 parts of the brine and 1 part of absinthe ;) Everyone else looks shocked when I describe it but I liked it :)
@@LeoMidori Its an anti-hangover elixir
Almost didn't notice Dr. Schwan was Brazilian (the way she said salmonella gave it away!). How cool she's in this. Thank you Dr. Schwan!
Given her pronunciation of Sauerkraut and some Rs I'd have said she's German - but then what does it matter. Her English is certainly better than mine 😀
In Poland where pickles and saurkraut are absolutely essential foods, we simply have different words for pickled with vinegar (kwaszone) vs pickled by fermentation (kiszone).
That is not true. "Kwaszone" is the same thing as "kiszone" and "kwaszone" used to be the OG term for lactofermented food ( it is still used in some parts of Poland and it is also a stanard term in food industry). Pickles made using vinegar are usually referred to as "marynowane" or "konserwowe".
@@kamillis7283 fair enough
@@kamillis7283 Same thing in Belarus actually, we use the same words for these different processes:)
Hey Adam, could you do some research about kefir and kombucha? They supposedly have a lot of lactic acid too - and kefir’s lacto-bacillum is said to withstand gastric digestion to colonize the gut. I’ve been trying both out of curiosity and I’d love to hear your take on those.
A video on that would be interesting too, being that I'm getting tested
due to their trace alcohol contents. I have noticed my gut health has gone downhill in the last year since I had to quit.
@Vladimir Novitski We have a lot of kefir in the Midwest Vladmir. The Smolyansky family (From Soviet Kyiv) researched for years and started their company in 1986. I get it just about everywhere from big box Walmart to the local stores and gas stations. Just as good as I've had in Europe. Lots of Polish here as well, a good thin savory pierogi can be found on tables all around during the Christmas holidays and polish delis year 'round, darned close to my cousin's pelmeni.
@Vladimir Novitski I've never in my life seen a baked pierogi, does sound interesting and probably delicious though. All are boiled , most are pan fried in butter to finish. The dough is usually thicker but some, like my cousin's , are thinner.
Not taking your comment too seriously, just pointing out America for the most part has a lot of cuisine from Eastern Europe as our population is heavily from there. Despite what you hear and see on TV.
@Vladimir Novitski When all of this crap is over I'd love to come and spend a few weeks with you as my guide! Your food and culture would be amazing to me.
We have a great many festivals celebrating cultures from all over the world, takes a bit of driving but most weekends there is one or two in the summer months (Pierogi Fest in late July is a must!). Definitely not as historical for a lot of it, but very enjoyable and great people to meet and learn from.
Thanks very much Vladmir, I appreciate the exchange.
@Vladimir Novitski I used to travel a few times a year for my employer, was lucky to have started in the 70's before the widespread turmoil in the Middle East. S America in the 80's. Many Asian countries in the 90's and 2000's that were former adversaries to the US. I'd always try to find a local worker that enjoyed and was proud of their heritage to spend time with during downtimes. Did the same for them if they came to the States. I really enjoyed learning about the cultures through them and the foods they enjoyed. Never did the touristy things if I could avoid it, exception of the natural and historic sites they were proud of. Everyone at that time was always respectful of the differences we all had and just enjoyed being people and sharing. I'm from the Great Lakes region of North America, the people I've hosted and I always enjoyed the visits. The ones from the Middle East and Asia got to experience the good parts of multicultural America, something not found in their home regions.
I don't do any social media Vladmir, so I guess we'll have to leave it at that. Hope the best to you and your family.
I took a "food facts and fads" class at PSU. What I learned there is how many "traditional foods" came about as a practical means of keeping food from spoiling as long as possible after harvest.
And how many were a yolo moment out of hunger. Thinking especially of certain cheeses and all of the the ways the Chinese ferment soybeans and rice.
Isn’t that obvious?
@@jujutrini8412 well to an extent, most mass production food facilities don't exactly credit the ancient methods they've refined with technology. Not to mention, them keeping the lid on the fact you can do it at home doesn't inspire their target customers to do so. Makes their pre-made product seem appealing due to convenience.
@@100GTAGUY I am probably older than you and have older parents and therefore knew my grandparents who were alive long before all this processed food came on the market. Also not from American culture so I probably look at food in a different way to you guys. I grew up around canning, pickling, smoking, and even more food preservation methods so when I see something in the supermarket I know how easy/hard it is to do x,y,z and make my purchasing choice accordingly. Sometimes I go for the time saving purchase but sometimes I go for the cheap homemade do it yourself method. I hadn’t grasped how different the mindset of young people in countries like America is.
what I always found funny is that odd pickle craving every Polish person I know experienced at some point in their lives. No matter whether they like pickles or not, there's always that one time a Pole needs that sour lactic fix. And there's actually some logic to that. My gradma always told me it's the sign of your guts needing some microbiota refreshment. I usually get that craving about three times a year and polish shops are actually well-equipped for that, cause a bottled pickle/sourkraut juice is an actual refrigerated drink you can buy here. And oh boy, when your body needs it, absolutely nothing is more refreshing.
As an American who loves to just drink kraut or pickle juice straight, it’s so great to hear that’s a legit thing in other countries
@@josephengel8263 well who knows. Meaby your family emigrated to US in early XX century and u might just have some central European geens inside you
Yeah, pickle juice was great to kickstart your guts when on hang-over. (Juszka - like my grandpa called it)
Its also that the bacteria are partially digesting the veg in a way your gut doesn't normally do. This converts some nutrients which could be the cause of said craving. Vitamin C from fermented veg is a real thing and cooking that VC destroys it, so there are a few ways we are losing out on nutrients.
Lacto fermentation was my new quarantine hobby in 2020! Here's my vote for you taking a deeper dive. Also, consider "dilly beans" which is basically using a dill pickle recipe, but using green beans instead of cucumbers. They fit in a jar much better.
I have 3 jars on the go right now. can I also suggest asparagus with garlic & black pepper, probably my all time favourite ferment.
Damn. I missed out on this whole quarantine hobby thing, for I was busy writing my PhD thesis. Now I have a kind of FOMO, for if there won't be another pandemic in my lifetime, I won't get the chance having a quarantine hobby...
I know a guy who used quarantine to learn all he could about quantum mechanics. All I did was becoming unnervingly nerdy about coffee. (Greetings to Mr. James Hoffmann.)
@@lonestarr1490 Give yourself an infectious disease and then you’ll have the perfect excuse to quarantine!
I’m Korean and grew up eating Kimchi, but have also heard it increases risk of stomach cancer. Would love to see a video on this superfood or carcinogen!
Kimchi could be salty, so the saltness might be the leading cause of stomach cancer? The same thing is said about Japanese cuisine, which tends to be salty.
@@tykep1009 There is very little sodium foods before we add it. I had to cut back, but before I did about 95% of the sodium I eat was added sodium.
Higher risk of gastric cancer in certain east Asian populations has to do with underlying genetic factors. This video lays it out nice and succinctly: th-cam.com/video/xy--51Jw6T8/w-d-xo.html
I thought the main risk of stomach cancer to Koreans was the amount of charred meats/soju we consume?
@@Nintentheheartless I guess a lot of BBQ will do that to you
I'm from Poland and currently live in Germany. It's really surprising to hear that people often don't know that fermentation of pickles and other vegetables is a thing at all. Even German sauerkraut is more often pickled (in some sort of vinegar-sugery water mixture) than fermented, which is an absolute crime against your taste buds.
When I studied in eastern Germany, my local Edeka even barrels of various fermented foods from which you could portion yourself. You might want to look for something like this :)
In my family (Polish family) we do canned lacto-fermented cucumbers. We sterilize jars, push cucumbers in with horseradish, mustardseeds, garlic and sometimes oak or grape leaves and other stuff, then we fill jars with ~60C 2,5% brine. It kills surface bacteria and softens cucumbers. We store them in basement for at least 2 months before eating. They're good for couple of years. We also make semifermented cucumbers - half fermented as you said - in open clay pot(only in season though). They're done after around 2 days. Salty, fresh, crunchy and delicious. Oooh... We drink leftover "juice" from the jars as well. Legends say it's a life saver when it comes to hangovers ;)
2 or 5%?
@@DeltaAssaultGaming 2.5%, some places use commas as decimal points
I've been seeing SO much recent research about fermented foods and the gut microbiome recently, and I've been really wondering what it would take to do this, since store-bought fermented foods tend to be premium products and (as she mentioned) the quantities for daily consumption are formidable. This video is super useful, informative and timely.
Look into sador katz videos and books, he really explains much of it very well. His dill pickle recipe is fantastic and perfect in flavour and textures.
@@kamilao4062 Seconding this suggestion. My wife has The Art of Fermentation and it has transformed our diets. It's incredibly easy, prevents a ton of food waste, and it's just good for you.
Most "fermented" products at the store aren't fermented.
The biggest thing is getting over the initial hurdle of taking that first bite. I think the best thing to remember is that there are only about 6 serious cases of food borne illness per year from fermentation in the US, and a vast majority are people improperly fermenting fish in Alaska. As long as it's at least 2.5% salt and submerged you'll be fine. I started making my own pickles a couple months ago and I've loved it. I'm actually working on getting a Chinese pickle going, that's super fun to look into.
I've been doing kimchi at home in a large kilner jar. The markup on store bought stuff is insane
'How do you pickle safely?'
a good question with more than one good answer
I'm studying cellular biology / microbiology right now. It is really interesting to hear about stories where it is all those little guys, the bacteria that I have gotten to know in this course, where they play the lead role! That graph really felt familiar and that is a good sign since often study material seems so abstract or pointless but nope - We of course have the good bacteria to thank for all our delicious pickles! Yum yum
These are my favorite pickles!!!
My wife's dad ferment them in a glass jars. Plastic jar cap allows exessive CO2 and water escape. After ~2 weeks they are ready. And you can store them 1 year safely. After a year they tends to change taste.
Adam, I've been making my own yogurt since the start of the pandemic. I would love to see you tackle the intricacies of yogurt making. I prefer less sour, and I have been working to perfect the timing of the cook for that.
I'm not Adam, but I've been making yogurt for the past 15 years; I just bring the milk to just-under it's boiling point, let it cool until it won't kill bacteria, then throw in a few spoons of old yogurt and leave it in a warm oven until it solidifies.
Have you tried different species? Personally I like Amasi/Amasai/Maas (these are all the same yoghurt). Is also a yoghurt that can be made on room temperature (how convenient!)
Thank you Dr Carla Schwan for sharing your knowledge.
I have gotten into pickling but never really had the confidence. The added vinegar is new to me.
Great useful video Adam.
I did lacto-fermented cucumbers this year. In my country Poland it's a culinary tradition of making sour pickles. We have something called pickle season in early July, when literally nothing is happening, even in politics, beacuse everybody is busy making pickles.
And the recipe that I used goes something like this. For 1kg of ground cucumbers, use 5l of boiled water and salt it with 3 full soup spoons of salt and let it cool down. Keep cucumbers in cold water for an hour so they will keep their crisp while fermenting. Then I put cucumbers in big jars together with 2-3 large cloves of garlic (maybe more if smaller), few slices of horseradish root and dill flowers. Try to left as few free spaces between cucumbers as possible, favorably fill them with dill leaves. Pour salted water in, and tightly screw the lid on. Keep it in a shaded place in room temperature for a few days until you see the fermentation process starting, then move the jars to the cooler place (like a basement).
So, pickle season is a Polish expression meaning a period when nothing interesting is happening?
@@erzsebetkovacs2527 Correct! And often media try to fill the summer void with low-quality info and therefore the expression "pickle season" (sezon ogórkowy) is usually used to describe an extensive media coverage of really not that interesting topic.
@@bartoszmackiewicz1666 So, this phrase is common with Hungarian "cucumber season" (uborkaszezon). Interesting.
Are you sure you are supposed to seal the lids tightly?
Bulgarian here the go to ratio my grandma told me and I've found in very very old cook books is 30-40g salt per liter of water , this is for cabbage and cucumbers but I'm pretty sure it will work on everything , 30 to 40 based on how salty you want the end product , did a couple of batches of cucumbers for the first time and they were great , really hard to find fermented stuff in the store so it was some nice nostalgia tasting these again.
That's how my wife makes her insanely good kraut.
Cabbage + salt + a little vinegar (1 TBsp per head) + garlic (2 cloves per head) + time (6 weeks)
Mix together and dump it all into a big earthenware crock, then cover with just enough filtered water to cover the mixture. Weigh it all down with a sanitized stoneware plate that's about the same size as the crock opening, and put a clean heavy stone on the plate. Once a week skim whatever excess liquid and gunk that forms. After 6 weeks you have kraut, skim one last time then remove the kraut from the crock and place in jars and refrigerate or pickle, whichever you prefer.
Dr Carla Schwan seems to be a great teacher - the graph and explaination were both very informative and easy to understand.
Hello! Great episode! Again here from Poland (I have seen some other comments below - cześć!). We (as Polish people but also all nations east of France I suppose) do not necessarily pickle our food in vinegar. We let them ferment on their own. I recently started that myself after eating delicious cucumbers and cabbage from my grandma and parents. There is a process (sterilize your jars in boiling water) and when all is right (old-timers have it into art) it is magnificent! Picked vegetables always taste like...well vinegar! Fermented stuff is a completely different taste! Fermented cucumbers are a staple with fish! Sour cabbage we add to pierogi's, and we make bigos (a cabbage and meat and wine ragout with smoked meats and plums). I suppose with some food you need to grow up with. But for half of Europe fermented vegetables, are as wild and crazy as hot dogs for Americans! I dare you to try it! :)
That sounds delicious! Care to share a recipe?
@@mellie4174 Ingredients:
2 kg of small ground cucumbers
2 small heads of garlic
a large bunch of dill with canopies
a piece of horseradish root and leaves - 10 cm
2 liters of boiling water
4 flat tablespoons of rock salt
you can also give: horseradish leaves, green oak leaves and leaves of blackcurrant, vine or cherry
You can safely fit two kilograms of small ground cucumbers in four liter jars. Of course, if you plan to pickle more cucumbers, you can double or triple the amount of all ingredients. The cucumbers should be fresh. The ideal will be those that have not yet fallen off the flowers from the tips. Both ends should be firm and the cucumbers firm and without discoloration or damage. Avoid overgrown cucumbers that are large. These wider cucumbers already have large seeds and will be empty inside and soft after pickling, so we avoid them.
Cucumbers, two smaller or medium heads of garlic, a piece of horseradish root, a large bunch of dill with flower umbels and rock salt are the basis for preparing pickled cucumbers. It is worth noting that silage also pretends to be using iodized salt. However, it is rock salt that has the most valuable minerals and trace elements.
Tip: To make cucumbers for the winter tough and firm, add horseradish root to the jars. You can also additionally add horseradish leaves, green oak leaves and leaves of blackcurrant, vine or cherry.
The recipe comes from here (aniagotuje.pl/przepis/ogorki-kiszone) and just translated part of it. Good luck and enjoy!
Here is a difference between ground cucumbers and greenhouse ones (www.gardenersworld.com/how-to/grow-plants/how-to-grow-cucumbers/)
man I've been loving your videos, I'm binging your channel these days, such great content, thanks for that
A correction for those wanting to make their own, the dill flavor in pickles is from dill seed, not the leaves. I too have made this mistake before.
Adam, you are amazing. Thank you for upping my kitchen game, and allowing me to try so many new things I probably would've never tried making... nor eating in the case of pickles.
Thank you, Adam. I've been fermenting for a year, and I really needed that lecture. People have started asking me questions that I should be able to answer. Now I can.
I love these science videos, Adam! I love watching your videos because I get to bridge my knowledge of biology and chemistry with the kitchen and not feel like I'm slacking off on my schoolwork. I enjoy the interviews and am impressed by the work you put into these educational videos.
Was literally just studying fermentation reactions for my test tomorrow, this is amazing timing.
I like to use a weight to hold the pickles below the brine, and use an airlock to let gas out while keeping any outside air from getting into the ferment. That combo has always worked great for me, for pickled cucumbers, saurkraut, and kimchi.
It’s amazing how timely your videos are Adam. Thank you
I've always been afraid of this process--but no longer! thank you.
Japanese pickle presses have a spring loaded "piston" than is a tad smaller than its container. After the veg is placed in said container, the lid is clamped down and a knob on the top of the lid allows the "piston" to be extended further down. The "piston" is attached to the end of the shaft with a ball joint, allowing the bottom of the "piston" to accommodate some unevenness of the veg. The lids are vented to allow bubbledge to escape. ✌😁
That sounds like a really cool design!
If you are going to do this I recommend not only the weights but a jar airlock. They are dummy simple to use and rather cheap allowing you to tightly close your jar as they prevent an airtight seal. With those two things and a glass jar and this is as easy as getting the right ratio. Just make sure your brine goes over the weights as well.
Love when you explain how the first/ancient people would have done something, always keep doing that please.
Cabbage is in season now at least here in Finland. I just set my first ever batch of sour cabbage fermenting just under a week ago. Great timing, now in mid-autumn there is still time to prepare home food stores for winter.
dude, there is ABSOLUTELY NO OTHER channel like yours. The infos you bring us, demystifiying tons over tons of cooking myths is unbelievable, not even counting the flawless presentation of every single video you make. This is the best channel about food to ever exist, and I thank you tremendously for that!
If I may suggest try to find a barrel for fermenting cabbage. In Poland we have special ceramic barrels with rim, that you pour water into and then cover with the special lid, that is submerged in that water. It creates a air-tight seal and you don't need to worry about air getting into, since CO2 will push out oxygen (kinda like those things for making wine that stick out of cork but much bigger :D). Also when making sauerkraut (kiszona kapusta, to not give all credit to our German neighbors ;)) my family usually adds the cabbage with dill in layers, stepping on each layer in that barrel to squeeze out most of the water from the cabbage, that water is then discarded. Also cabbage should be shredded rather finely. And after few week sauerkraut is ready, now we don't even bother to transfer it into jars or anything, just top up water in that barrels rim, to not let oxygen in and it lasts whole year easily.
As for pickled cucumbers, we have special jars for fermenting them too, the ones with a sprint on top and rubber gasket that goes between the top and jar proper. Basically foolproof, just stick all ingredients in, cover with enough water and add enough salt, close the lid and in few weeks pickles are ready. And yeah, as someone said, smaller ones tastes best and everyone eats them first :D. There's very popular soup in Poland made from pickled cucumbers, zupa ogórkowa, very good and apparently healthy.
There's also soup made from juices from boiling sauerkraut, called kwaśnica, very popular where I'm from.
Just fyi, in the US we call such barrels “crocks” :)
Still, most people in Poland don't bother with special jars. You can use anything - from any glass or ceramic jar or even plastic basket and just weight everything with something pressing down a plate to preparing them in plastic bottles (it helps to use the tiny cucumbers for pickling for that).
There are plastic lids for fermentation, that keep air out and let the CO2 escape. I watch a youtube channel Steffi kocht ein (this is German, Steffi is canning), and I think they offer also subtitles. The channel quickly became very popular. They also have a company (since the early 2000s), which means they can order special glasses or lids from the industry - they just have to order a few hundredthousand. - Anyway: the fermentation lid works for any regular large (or at least medium sized) glass with a wide openening. This is more practical than having a barrel standing around. The large glasses can be used year round (for storage, vinegar making, etc.) There is no barrel or special ceramic pot standing around.
@@Ellestra the large clay pot with the water rim is traditional in Austria and Germany. They are still sold a big one is around 70 Euro, so it must be an important feature. To be sure - glasses with metall lids were not available back in the day.
if the sour liquid has contact with a metall lid the later will rust, so that would be my objection. If handled carefully (not moved around) the rust (and whatever corrodes from the metall) should not get into the food, and the lids can be replaced for the next fermentation. (the shop I mentioned sells lids for replacement and they can be combined with glasses from industrially canned food, there are certain common sizes and types. But I think they only deliver with in the EU, and maybe not even into all the member states. They supply to households as well as small business.
It is also likely that in the past the lids would have been too expensive to be thrown away, even when such things could be produced.
It likely was cheaper (on the long rung) and easier to produce the clay pots with the rim. The other option was the barrel made from wood and weights to submerge fermented food - mostly sauerkraut.
@@franziskani Standard glass jars with metal lids work fine for fermentation. In fact that how sour cucumbers and even sauerkraut are usually sold. And that what you would use at home if you were preparing them for long term storage (you can pressure seal them - just like vinegar based ones). But it is not advisable to use metal containers.
Been fermenting my own stuff for many years, the biggest thing is definitely the container as that greatly determines how safe it is and the kind of steps you might have to take to keep things safe.
Some things to note is that Kimchi is often eaten during the fermentation process, with the leftover batch going full sour and long-term stored. The fizz is a key sign that the kimchi hasn't gone full sour.
Maybe I'm just not accustom to it? I always full sour my ferments, maybe there's more "gut flora" when eaten partially active. From my own tastes and that of most others I've shared some with we end up preferring the more sour.
In Romania we don't pickle anything with fresh dill, instead we use the seeding flower heads of the dill plant, in dry form, they sell them at the stores and in the markets but some grow their own,
I would definitely recommend it to anyone that wants to pickle some stuff this year, it's a much nicer flavor profile than from the green leaves, but you could also do both.
Most 3d printed parts are made of lactic acid too, it's really good stuff. PLA, is just poly lactic acid, and it's what most 3d printers use.
they are delicious
In Russia, making our variation of sauerkraut at home is still somewhat popular. You just mix a bunch of cabbage (and I mean a LOT), some carrots and cranberry, salt and a bit of sugar, leave at room temperature (in a vat with a big rock to keep the solids down) for a day or three. Then you can store it in the fridge or on the balcony during the winter. Tastes miles better than anything store-bought!
My grandma makes a good bucket or two of fermented cabbage if the harvest is good, never seen people add cranberry though, only carrots
@@crazydragy4233 Yeah it was my grandma who taught me. I guess there are regional and family variations, like always)
Fresh cranberries? Or the shop-bought ones, which come already sweetened with sugar?
@@erzsebetkovacs2527 We used to go to a marsh in the country and pick them ourselves, then freeze them. So that's what we used. I imagine if you have sweetened cranberry then it's okay so long as you don't add any additional sugar
I've been looking forward to this episode ever since you mentioned it in your pod!
Always have mad respect for Adam and everything he does. Wishing you the best for future projects man!
I *LITERALLY* just finished fermenting those same dill pickles from that recipe! I'm going to taste them and hopefully can some of them this weekend. What a weird coincidence. I love how, after about 2 or 3 days, you start to see the cloudiness of the LAB starting to spread, it makes you feel so glad to see it.
I'm literally in my lab, glove on, in front of a clean bench hand deep in Lactobacillus acetotolerans and still clicking on this video thinking "yeah, I might need to know that".
I've been waiting on this video for a while! So excited to try it for myself! Thanks Adam!
My grandma fermented cabbage in a special barrel, which helped with speedy fermentation. It was never washed, only scrubbed between uses. It was able to store cabbage for whole winter and spring at room temperature.
I have been making my own kimchi and other Korean pickles for decades, but for several years the hobby fell by the wayside. Then during the pandemic I developed pre diabetes And I resumed making almost all my own meals! Making fermented pickles and other time intensive recipes. And they do change how your body works. I can proudly say I now no longer need drugs to balance my blood sugar, and while other dietary changes and exercise have helped, I have no doubt the home made pickling without Vinegar has been transformative.
Well, this was timely. I'm about to have a hot pepper harvest and was looking into lacto-fermentation for hot sauce. Since I'm not generally a fan of any fermented foods, I'm understandably anxious. This was really awesome and helpful, going over some of my concerns quite nicely and helping direct my purchases for fermenting lids/weights. Thanks. :)
I do peppers all the time. And I love pickling tomatoes, as well.
so no bread, cheese, wine, or beer for you? :) Or yogurt?
@@nsbioy Pretty much. :) Most cheeses I like and non-Greek yogurts, so the dairy ferments are generally tasty. Bread can be sketchy for me and I react poorly to all alcohol (flush reaction). And I just don't dig the taste of most anything pickled. Was hoping I'd grow out of it as I got older. Pickles would be a cheap and healthy snack, lol.
Very well done, I really enjoy the science imparted by Dr. Schwan. I love educational videos like this.
This video is enlightenment and full of information, THANK YOU
I've started using a thin layer of oil on top of my pickles around the weight to prevent the mold; it creates a nice anaerobic environment but also lets air through (you still need weights unless it's a thick oil layer)
great idea!
We make a lot of spiced preserve pickles with no water like kimchi and add oil instead. A thick layer of oil on top is mandatory.
to keep my lacto-fermented pickles crispy longer, i pickle them with whole mustard seeds. there's a compound in there that helps keep them crispy! and if you keep the seeds whole, it doesn't impart an overwhelming mustard flavor, in fact it's extremely subtle. very tasty.
Thrilled to see the time lapse made it into the video!
Fascinating! I have spent more than a year working in S. Korea and love kimchi. After coming home to the States, I miss that.
Also, 120 grams or kimchi seems a lot, but 120 grams of sauerkraut is very doable. In poland we often eat way more at once, as a side dish during dinner. If you spice it properly it can be just as interesting of a flavour as kimchi. My favourite thing is probably cumin seeds, but not everyone likes them.
Do you eat it warm or cold, also please share some of your spice recipes. I love sauerkraut but my husband doesn't like it as much and I'd like to make it so that he falls in love with it like i have
But it is usually cooked right? Then the bacteria got killed though.
You could also test pickling with leaven. It's a thing in Hungarian (+probably neighbouring) cuisine. You basically put the pickles in a jar (cut off both ends and in perpendicular from both ends just not cutting it in 4) with some garlic, dill on top & bottom, true leavened bread, (just a slice is enough for starter,) water mixed roughly 1 spoon of salt per liter to fill it up, including the slice. Then put it traditionally in the sun, or anywhere warm for 2-3 days. Don't forget to refill the water. It should have a strong taste, almost reminiscent of carbonic acid in strength and not be soft.
Glad to see the time-lapse shot worked out! 🙌
I learned this from my grandma and it always was like a kind of magic to me.
In Poland lactobacteria fermentation is present in every cellar, kitchen and on every table, ogórki kiszone (lactopickled cucumbers) kapusta kiszona (lactopickled cabbage), tomatoes, beetroots, cucurbits and every possible freshly picked berry vegetables. Good breded cutlet with mash and pickled cucumber still is very common option for dinner.
One ingredient my dad and I use for our pickles is oak leaves rather than tea or lime, but if you don't have any of those if I'm not mistaken you can just increase the bay leaves and mustards a bit to get them a bit crispier.
Love this! I also use National Center for Home Food Preservation…for everything preserving and canning. Thanks!
Thank you for all your content Adam, you are one of my fav channels!
Great video! would love to learn more about meat lacto-fermentation. One of my favorites is a Thai pork sausage called Naem! (which is often consumed raw as well as cooked)
I made my first batch of fridge pickles recently! Love Adam's recipes - Super tasty!
Fridge pickles, though, are not fermented (since refrigeration more or less stops fermentation). Fridge pickles are normally the vinegar type of pickling he describes, not fermentation.
@@michaelham2366 I think the OP knows that, which is why they added the modifier "fridge."
One of my favorite videos of yours! Keep it up!
Vacuum bagging is perfect for this. When the bag inflates with co2 snip the corner and reseal. Great Vid.
the way you intertwined the interview with your commentary is truly amazing
Ukraine is here 🇺🇦 as well as Polish people, we do this salt veggies starting from October. It’s really delicious and healthy, in addition it’s quite tasty. 👌🏻
Great work, thank you for the scientific approach!
Literally have been reading about all this for homemade hot sauce. Glad you made this video.
A really great way to lactoferment, I find, is vacuum sealing. I learned how to lactoferment from the Noma Guide to Fermentation and I really recommend fermenting stone fruit like nectarines or plums. Absolutely phenomenal.
Ripe or unripe fruit?
Proper Dill pickles are; cucumber, Dill flower (not that herby part, a fragrant, rooty Dill flower and stem), horseradish root, garlic and optionaly very game changing, some leaves, fresh oak, red Berry leaf.. Amazing stuff. What a difference this combo makes.
fresh oak as in bark?
@@picgmr1575 lol, some leaves
I've been waitin' for this one and the timelapse! Looking forward to the gut health video :)
I make my own variation of sauerkraut, and I hope more people can learn not to overthink the process, as it is an excellent addition to everyone's fridge.
This is the video I’ve been waiting for, I’ve been ferementing for the last year and reading a lot about it, but there is always something new from Mr. Ragusea. Doing scorpion peppers and strawberry’s currently.
Hey Adam! You probably hear this a lot, but you really helped me be less scared and overwhelmed about getting in the kitchen. You were the one to help me understand some of the absolute most basic things, and a lot of more advanced things too. Cooking is fun for me, and I wouldn’t have found that out if it wasn’t for you. Thanks Adam
To be honest, I’ve always just put in a guesstimate amount of salt, and in my many years of pickling, has always worked just fine
I don't think my grandmother weighs her lactofermented dish salt either and they usually turn out fine. Though she's the first one to not let you use a jar if it isn't perfect in taste or smell xd
Truly a beautiful symbiotic partnership. Thanks little bacteria bros!
Fermenting peppers makes their flavor EXPLODE. It's incredible!❤
A big stick of horseradish is great flavor for dill pickles.
Also, it's traditional to use a tannic grape leaf, or an oak leaf to keep the pickles crisp.
Something I do that wasn't mentioned here is that I always have sauerkraut fermenting because, in my now 7 years of making it, had only one batch go bad...ever. This makes my success rate with it well above 99%. Other veggies are a bit trickier than cabbage...especially carrots (probably because of their higher sugar content). So...what I do is use a bit of good sauerkraut liquid as an additive to basically all of my other lactoferments, which both seems to kickstart them, and improve their success rate. Carrots are really the toughest of all...I have probably a 5% failure rate on carrot ferments, though the most common issue is just wild yeast that creates a bitter floral flavor that really doesn't mesh well with the pickle acid flavor. The rub here is that fermented shredded carrot makes for one of the finest relishes you can ever add to rice-based dishes.
Thanks for stopping by, Adam! Come back any time!
The time-lapse worked!
Literally just learned all about fermentation in biology today. Great timing as always. Not the first time this happened either.
I've never tried it, but I have heard that oak leaves can also keep pickles crisp with their tannins
Grape leaves too. Also bay leaves. Green tea is recommended over black tea because black tea discolors the food.
Great vid! One of my favorites yet.
Congratulations on the spectacular video! Will be coming back here in the near future for sure.
Thanks Adam for reminding me how to calculate a proper brine ratio for lacto-fermentation. Unfortunately, I've started all of my hot sauce ferments last night and used volume (5%) instead of weight... Let's hope for the best!
i usually go with a 4.5 - 5% brine, no problems so far, just make sure your ferment doesn't have any exposed solids on the top, keep everything submerged
Having two 10 liter containers, one with cucumbers and one with carrots, cauliflower and cabbage. It is awesome. We typically do 40g salt per liter of water.
I was just planning to start fermenting some homegrown peppers today. Perfectly timed video
Great video! I’m always pumped each week for your videos 🤘🏼🤘🏼
You have to be careful with peppercorns and other seasonings, because that can float to the top and grow mold, even if the larger vegetables are weighed down.
Part of my family is from a town famous for its lacto-fermented pickles, so we always make plenty during summer and eat them the rest of the year. We usually use simple jars, and instead of weighing them down we just fill them to the brim andd place a couple crushed aspirin pills on top, seems to help with fungus trying to grow on top
Thanks, Adam. This is very much the sort of thing I was needing to learn.
