In my experience, grinding (wet milling) the nixtamal is the most difficult step to perform at home. I'm currently cheating a bit due to lack of proper equipment: I blend the nixtamal with the same amount of water by weight, pour this into a mixing bowl and then add enough masa harina until the masa reaches the right consistency. Thanks for these great videos and outstanding products!
So you're saying that I should buy a really expensive restaurant grade mill so I can make masa at home every once in a while? Based on what I saw and learned when I was in El Salvador, this series makes masa production to complicated. If a hand crank metal grinder is good enough for a little Salvadorian grandmother then it'll be good enough for me.
Hi Michael, thanks for the feedback! There are definitely many ways to make excellent masa. That's great you hear you've found a method that works for you. To many wonderful masa dishes.
This thing is great but ultimately outside my reach. It would be nice if you could someday engineer a machine more in the $600ish dollar range. I only need to grind 2 lbs at a time. That makes a rather large amount of tortillas for eating at home.
A Molinito would be great and is on my wish list. That being said, I would love to buy a nice big sized metate but I simply can't find one in the US. Your company could probably corner the market if you were to import and offer those.
@@jaredmercado7045 I was able to find someone on Etsy selling them. Ordered and delivered in two days from Mexico. It is exactly what I was looking for. Great service. I highly recommend Alejandro's Etsy shop: ManosdemiMexico
I learned to make great tortillas by watching your videos and using the Doña Rosa press. I'd love to get a Molinito one of these days. I've made masa before using a wet grinder that grinds grains and legumes, but it never came out exactly right. One of these days, I will take the plunge...
@@Masienda Also wondering whether this unit is the smallest powered one you are planning to carry. I was thinking that a smaller "prosumer" model for home use would be very interesting--something about the size of a nice Rocket or La Marzocco espresso machine.
Hi Ellen! Thank you for your question. Indeed, it's the smallest one we are planning to carry. Our molinito is a countertop stone mill, designed to be used by devoted home cooks and small food concepts alike. As a result, it's designed to house its compact but mighty motor needed to achieve fine stone-ground masa and fits on most kitchen countertops, while also plugging into your standard 110V outlet at home. While we understand its probably larger than your typical espresso machine, Molinito is compact compared to most masa grinders on the market at the following dimensions: 26.5″ (l) x 14.5″ (w) x 18″ (h)
I have the wondermill jr hand crank that has stainless steel plates (you can add a drill attachment instead of cranking). But even then getting it to masa can be a challenge.
You're absolutely right-grinding nixtamal into masa can be tricky with some hand-crank mills, even with a drill attachment. The plates often aren’t designed to achieve the fine, smooth texture masa requires. That’s why something like the Molinito, which is specifically designed for nixtamal, makes a big difference-it’s built to handle the unique grind nixtamal needs! Let us know if you have any questions.
@Masienda Yes I do love that machine but price wise is rough plus counter space. I blend the soft kernels first to pebble size, then add to the handgrinder or my molcajete (great for small batches). I need to get a metate lol. Love your videos. Thanks for the content.
A large mortar like the ones used for mochi dough could work, but it may be a bit challenging to achieve the fine texture needed for masa. Corn grinding requires more force and a specific texture to create a smooth dough. Typically, a metate or a stone grinder designed for nixtamalized corn would give you the best results, as it helps break down the kernels evenly.
Thank you, Andrew! It is quite quiet, believe it or not. I'd say quieter than a blender, if that helps with perspective? We have neighbors here at our office who wouldn't be too pleased if it were louder than that :)
Hello, I am having a problem with my Molinoto machine and would like to ask some detailed questions about doing some self repair. I am in Japan so it is not possible to send it back for repairs. It is an amazing machine and very happy with it but like any formula 1 race car sometimes things need repair. Please let me know who I should speak with. Thank you very much.
Hi! Thanks for writing and being a Molinito user! Please reach out to: molinito@masienda.com with any specific questions. We also just released a series of videos for helping repair and take care of your molinito: th-cam.com/video/p6TIM3uLnAM/w-d-xo.html. THANKS!
I'm curious where the sand comes into play, I see it offered for sale as well as the stones but I don't see what you do with it, not that I can be buying a molinito, I'm just trying to understand how it all works
Hi John, great question! Once the pair of grinding stones have been spent and are no longer sharp enough to produce a fine masa, the sand is used to calibrate the stones down to a flat porous surface. This is done to prepare the stones for resharpening.
Thank you for your reply, the issues I am having is beyond the videos that I viewed. The problem is that the bearings are loose and coming out from the housing and the back joint for the shaft is really loose and the there is no pressure on the stones and the shaft does not move and the spring does not move.The other machine that is the same model'' 3rd model in the video'' The bearings are solid and do not move around and the back joint is tight that has the U shaped cap for the handle arm to apply pressure is also tight and does not move around like the machine that is having the problem. If I put something in front of the shaft I can make the spring move but the shaft does not move at all. Let me know if you know what the problem is or if you need me to make a video for you to see. Thank you and hope we can get the machine going again. Gracias.
Hi, thanks for asking! While we've ground a few seeds and nuts successfully, we have yet to try veggies. It would likely be fine but may may wear down the stones quicker than anticipated.
Hello! We recommend resharpening the stones every 3-4 months, depending on use. It is not necessary to replace them entirely until they are completely worn down--which can take years, in some cases. Please let us know if you have any additional questions at info@masienda.com Thank you! Tony
I don't think you just want to let it dry. I would think your masa might get moldy, or fermented before it dries into masa harina, depending on the climate you live in. I think what you would want to do is put it in a dehydrator or oven on very low heat to dry it out.
I have milled some in advance and just froze it. It seems okay to me, but I’m not a pro at this at all. I do it with my grain mill and it can be tedious to clean it up, so I run large batches and freeze meal size baggies of it and take out when I need it. 🙂🌮🌽
What I have heard some people doing is after nixtimelizing is they dehydrate the kernels after they have been washed. Then at a later date run them through a grain mill. Not sure if that effects the taste or not.
Hi! Nothing wrong with the masa from your local shop. We are happy to offer non-GMO heirloom corn and masa harina made with just corn, water and culinary lime; allowing the flavor of the corn come through.
Can you just use a mortar and pestle? Maybe even better a wooden plunger in an ancient hole in a rock that was used by indigenous for hundreds or thousands of years? I can't recall what those ground down holes are called, but I bet they made the most FANTASTIC tortillas. I'm going to research all this.
But then since most people don't have access to Anasazi "holes in rocks," can't you just use an old school cast iron hand grinder? I looked it up before I edited this, and there's nothing on TH-cam about using a mortar and pestle or a cast iron grinder. I think there's a void here.
Hi Hector--Our Molinito is not yet NSF certified. The cost for doing so is currently prohibitive at our scale, however, its component parts are all restaurant/food grade, 304 Stainless Steel, etc. Please reach out to us at info@masienda.com if you have any additional questions at all. Thank you! Tony
Hi Angie! Our corn (and masa) is all certified Non-GMO.The majority of our farmers are smallholder, subsistence growers (and not certified organic). We are not able to 100% guarantee that something (i.e. pesticide) isn't used within the network of 2,000 farmers. However, we always encourage and prioritize purchasing from growers that use regenerative organic practices.
Hi Elias! We'd love to but it will increase the price per unit quite significantly. As we scale, we'll work on bringing on additional certifications. Please don't hesitate to let us know if you have any more questions.
I want this machine so badly I can taste it. I've wanted a home molino for years. I can buy masa, so my husband would kill me if I got this, but I want to prepare my own choice of corn, and I'd like to adjust the grind for tamales. Unfortunately, this machine is still too large for my space, even though it's significantly smaller than a commercial model. I suppose the size is necessary to get the horsepower necessary for the work, but where would it fit in an ordinary kitchen?
Yeah, but how many of us are going to buy that machine just to make tortillas for our family. Can you show us other ways to grind an acceptable product using a hand crank machine or other more everyday option?
Hi! We're working on a few home options, but in the meantime, we have more information on getting a puff at home using a hand crank (hint: it takes three passes through the grinder). Check out masienda.com/on-masa/masa-weekly-formerly-monthly-white-bolita-oaxaca/ with tips on how to achieve that puff using a hand-crank.
I’ve been looking for real nixtamal mass since I moved to the us, bringing it frozen every time I go to Mexico, begging friends and family to bring when they visit, so heck I’m getting one just so my kids can tell what a real tortillas tastes like!

Are those cookbooks on the shelf behind you? If so which cookbooks would you recommend? I have your masa book
Do you guys make dual voltage or 220v? I have a tortilla business and feel that this machine would meet my needs. I've been hand milling.
Hi there! Our Molinto motor is 1 HP, 110-127 Volts. Here's the link to it on our website: masienda.com/products/molinito
Would a large mortar, like the ones the Japanese use to make mochi dough with rice, work?
A large mortar like the ones used for mochi dough could work, but it may be a bit challenging to achieve the fine texture needed for masa. Corn grinding requires more force and a specific texture to create a smooth dough. Typically, a metate or a stone grinder designed for nixtamalized corn would give you the best results, as it helps break down the kernels evenly.

Is it possible to grind it to a flour for later use? Do I have to just let it dry after grinding? Anyway great videos.
Yes.
I don't think you just want to let it dry. I would think your masa might get moldy, or fermented before it dries into masa harina, depending on the climate you live in. I think what you would want to do is put it in a dehydrator or oven on very low heat to dry it out.
No, wet masa will not turn into dry masa. You will en up with Tejuino, fermented corn drink.
I have milled some in advance and just froze it. It seems okay to me, but I’m not a pro at this at all. I do it with my grain mill and it can be tedious to clean it up, so I run large batches and freeze meal size baggies of it and take out when I need it. 🙂🌮🌽

Hi Nigel, good question. After prolonged use, it is inevitable that particles of the stones themselves will gradually be worn off into the masa over time. This is true for not just traditional basalt stones, but
also synthetic stones or the metal plates common to hand-cranked home grinders. Synthetic “food-grade” stones are touted for their durability and slow wear; however, many contain aluminum oxide, which molino purists avoid, on account of personal preference. Basalt, in contrast, is made up largely of calcium oxide and magnesium-alkaline metals that, as Azteca puts it, “naturally run through the blood stream,” making it preferable in not only function but also form. As for metal hand grinders, most are food grade and composed of iron and tin, which are considered safe in small quantities (as the trace shavings created during grinding would be).
