    Since discovering fermented tofu, I have been using it a lot. Whether it is in soups, marinades, or as a dipping sauce, it can be used in many dishes to add extra flavor, umami, and some cheesiness.

    The thing is, fermented tofu is not that easy to find and let's be honest, I wanted to learn how to make my own. Here is a guide on how to make fermented tofu (also called chao) from scratch!

    📘 What is Chao?

    Chao (which is its Vietnamese name) is tofu that is fermented for at least 1 month in a brine that consists of water, salt, and usually rice wine. According to some books, the technique to make fermented tofu appeared 200 BC in China.

    It is quite salty, sometimes spicy, and has a very soft texture, almost like a paste that you could compare to blue cheese. When chao is fermented for a long time, it takes a strong flavor, that reminds me of a strong camembert.

    What's great about chao is that it keeps for months, if not years in its brine!

    🥣 How to Make Chao?

    Making chao is easy but requires some patience!

    Before starting: As with most fermented recipes, taking care of hygiene is critical to the success of the fermentation process. So I recommend using gloves while handling the tofu to prevent bad bacterias.

    Preparing the tofu

    It starts with the tofu that is boiled for a couple of minutes in salted water. This step not only helps kill some bacterias, but it also helps the tofu drain more water.

    Next, you want to place your tofu on several sheets of kitchen paper towel, cover with more paper towels, and place a weight on it to press it and remove excess water. I usually use a large iron skillet that is quite heavy. Leave your tofu like this for about 1 and a half hours and change the paper towel as needed if it becomes too wet.

    Fermentation

    Next, cut your tofu into 1-inch cubes. Place them on a plate lined with kitchen paper towel, then place another piece of paper towel on top, and cover the whole plate with plastic film.

    Now you want to let the tofu ferment for about 2 days at 77-86°F (25-30° Celcius). So as you can guess this recipe works best in the summer, but can also be done during winter if you have a warm spot in your house.

    After 2-3 days, the tofu should be slightly orange and a bit stinky (see photo below). It may have some white mold as well, that's okay. If you see black or blue mold, just scrape it off. Quick tip: if the tofu is not stinky enough when you put it in the brine, you will end up with a mild chao, if it is already stinky your chao will be stronger.

    The hardest part is now done!

    Adding to the Brine

    The tofu now contains some natural cultures and molds that will work during the fermentation process.

    To prevent the tofu from going bad, we need a brine. It consists of boiled water mixed with salt, sugar, and rice wine (or vodka). Place the tofu cubes in glass jars and cover with the brine.

    Optionally, you can dip each tofu cube in chili flakes, it makes the chao more flavorful and gives it an appealing orange color. If you plan on using chao to make cheeses, simply omit the chili.

    Once your jars are filled, secure with a lid and place them in a dark place at around 68°F (20°C) for at least 3 weeks.

    The longer you let it age, the stronger and softer it becomes. I found that after 6 weeks, the tofu is already creamy and has a nice cheese flavor.

    💬 FAQ

    • Can I omit the wine? I would not recommend it, it helps with the preservation of the tofu.
    • I am getting a lot of black mold on the tofu, is this normal? No, you shouldn't have any black mold. If that is the case, start again and make sure all of your tools and plates are clean. Use very clean hands while handling the tofu, or handle with clean chopsticks.
    • How long can I keep Chao? You can keep chao in your refrigerator for up to a year. I personally had a jar that I kept for over a year and the chao was still perfectly good!

    🥢 How to Use Chao?

    Chao can be used in a handful of ways:

    • Dipping sauces: Mash a cube of chao and mix it with some lime juice, sugar, chili, and a little bit of water to dilute. The sauce can then used as a dipping sauce for steamed veggies.
    • Vegan cheeses: Since chao is packed with umami and cheesiness, it's perfect to add flavor to your vegan cheeses! Add half of a cube to vegan camembert or smoked cheese when blending the cashews for a deeper flavor!
    • On top of rice: Add some chao on top of steamed white rice and slightly mash it using chopsticks. Chao will add saltiness and cheesiness!
    • Stirred into soups: Perfect to take your soups to the next level, you can use it in place of miso.
    • Marinades: Combined with soy sauce, sugar, and sesame oil, this fermented tofu can be used as a base for marinades.

    Cuisine Vietnamese
    Servings 2 medium jars
    Prevent your screen from going dark

    Ingredients
     
     

    • 1 pound firm tofu, cut in half
    • 4 cups water
    • 1 tablespoon salt
    • optional: ¼ cup chili flakes

    Brine

    • 1 and ½ cup water
    • 3 tablespoon salt
    • 1 tablespoon sugar
    • ¼ cup vodka (or ½ cup rice wine)

    Instructions
     

    • Before starting: I recommend using gloves when handling the tofu to prevent bad bacterias and mold from growing.
    • Bring 4 cups of water with one tablespoon of salt to a boil in a medium size sauce pan. Once boiling, add the tofu and boil for 4 minutes.
    • Remove the tofu from the water and place it on a few sheets of kitchen paper towel. Top with more kitchen paper towel and place a heavy weight on it to press the tofu and remove excess water. I usually use an iron skillet. Let it drain for about 90 minutes, changing the paper towel as needed if it becomes too wet.
    • Line a large plate with two layers of kitchen paper towel, or a clean towel. Cut the tofu into 1-inch cubes and place the cubes on the plate, leaving about 1 inch between each cube, so they don't touch each other. Top with another sheet of kitchen paper towel and cover the whole plate with plastic film. The plastic film will prevent bad bacterias from reaching the tofu.
    • Place the plate in a dark place at 77-86°F (25-30°C) and let it ferment for 2 to 3 days. The tofu will have taken a light orange color and will have a stinky smell. You may also see some white mold as well, this is okay. If you see blue or dark mold, scrape it off.
    • Prepare the brine: combine 1 and ½ cup of water with the salt and sugar in a saucepan. Bring to a boil and boil for 1 minute. Once boiling, remove from heat and let it cool completely. Add the vodka and stir to combine.
    • Transfer the stinky tofu to clean glass jars. If you want to make it spicy, dip each tofu cube in chili flakes before putting it in the jars. Pour the brine into the jars to cover the tofu. Close the jars with a lid and place in a dark cool place (around 68°F - 20°C) for at least 3 weeks. The longer you let it ages, the stronger and softer your tofu will be.
    • For extra flavor, you can add about ½ teaspoon of sesame oil into each jar after the 3 weeks have passed.
    • Use this fermented tofu to make dipping sauces, to top rice, add to vegan cheeses, use in marinades, soups, etc.

    Notes

    For a quick dipping sauce, mash one cube of fermented tofu in a small bowl. Add about 1 teaspoon of lime juice, 1 teaspoon of sugar, and sliced chili to taste. Feel free to add a couple of tablespoons of water to taste if it's too salty. Use this sauce to dip steamed or roasted vegetables.

              Hi Zsuzsa,
              You should actually see an orange tint, and not too much white mold (that's not the goal). Regarding the dark spots, it's not okay. If you just have a few, scrape it off, however if there is a lot of black mold you should start again.

      Hi Thomas,

      thank you for making this recipe, I have wanted a recipe like this for some time, thank you!

      Is it possible for you to develop a cheese recipe with the chao? For example, here in Canada we can buy a cheese named "chao" that is made in Greece. This sliced cheese is very well known in North America. There are simple ingredients (i.e. the plain one). I can email you the link if you wish. Do you think you could help us with this? Thank you!

          I’m glad to hear this as I was wondering how your recipe for blue cheese would turn out adding some of this chao.
          I also saw a recipe for super stretchy cheese using a bit of this chao and made with potato or tapioca starch and coconut oil. It looked like something you could try but in your way which I would love to see

          I’ve been making a lot of variations of this. It’s really interesting...just like in dairy cheese making, small changes can make big differences!
          I’ve found that the type of tofu makes a huge difference in texture, regardless of how long I press it. There is a bulk tofu I get from our local coop, it is with this that I make what I call the feta. The prepackaged tofu , even the kind that says extra firm, comes out as a much softer product, and ferments much faster. It reminds me of some of the true ‘’stinky’’ cheeses (washed-rind cheeses that I used to make, and loved, such as Tallegio, and even reminiscent of Epoisses! I’m truly amazed.
          Also I played around with adding schezuan pepper instead of chili flakes and it is mind-blowingly good.
          Some Vietnamese friends can’t believe I am making chao and they absolutely love it too.
          Again, thank you!

            Yes, tofu can differ a lot depending on brands. I never buy mine at the supermarket as I find it to taste bad and has a "grainy" texture. The one I get from the Asian market is also called firm but is softer, as you said. I'm glad your Vietnamese friends like your chao 😀

      Thanks a lot for this recipe, it turned out very tasty. I used some fresh red chilli slices, and the tofu turned out spicy, but very creamy, flavorful and delicious. For sure not as pretty as in your pictures though. It has a slightly grey tinge and floats, so I had to use an impromptu fermentation weight (a slightly smaller lid covered in cling foil) to keep it in the brine.

      Thomas, it is nice to see a recipe for this dish. One comment though: "Chao" means stinky, it does not mean "stinky tofu". The word for tofu is pronounced "doufu". "Chao doufu" is stinky tofu. Happy cooking!

        Hi Shawn,
        What I'm referring to is fermented tofu, not stinky tofu. "Chao" is the Vietnamese name for it and it doesn't translate to stinky, it refers to this condiment.
        I guess you are talking about Chinese stinky tofu that is often fried and served with a sauce. This tofu is used to make sauces and marinades, it is not eaten on its own, or fried.

        Hello Nusha,
        The main reason is that your tofu was not fermented before putting it into the brine. The fermentation is essential as it will change the texture and flavor of the tofu.

      Also is there anyway to make this shelf-stable?

        Yes, boiling the tofu not only helps drain some water and let the salt penetrate, but it also kills possible bacterias.
        It is shelf-stable for quite a long time however I prefer to keep in the refrigerator to keep longer.

      Hello, I have tried this twice now and each time my tofu develops a black Mold and the last batch started smelling like Ammonia. I’m not sure what I’m doing wrong. I’ve tried to keep anything g that touches the tofu clean each time. If you leave it more than 2 days, can bad bacteria infect the tofu causing my issue?

        Sorry to hear that! At which temperature are you fermenting the tofu? Also, do you keep it covered?
        Try using gloves when handling the tofu, or clean chopsticks so you don't touch it with your hands.

        Just wanted to mention again...in all the batches I have been making...the packaged tofu that is available locally is soft, even though it is called xtra firm and I press it well. This kind of tofu needs to be fermented for a much shorter time. If I let it go a full 2 days it starts to develop black mold, and the finished product is melty soft and falls apart. So I ferment it for a shorter time. Even though there isn't much orange mold, it turns out perfect. The firmer tofu I make or buy in bulk needs a longer ferment time, or it stays hardish and grainyish for a long time. You can test a small piece as it is fermenting to see if it is getting too soft or staying too firm and adjust your ferment time accordingly. The ammonia smell seems to happen if I ferment too long....

          Thanks for your input Kelley. The higher the moisture content of the tofu, the easier it is for mold (good and bad) to develop.

            Thanks both Kelly and Thomas. I tried for a 3rd time and and only left covered for 2 full days. I saw a few Orange spots, but no black mold and no ammonia smell. Got it all in the brine and did a mix of as is and chilli flakes. I think you are both correct. The 2 batches that went off were left longer than 2 days. Looking forward to trying in a few weeks. Your Vegan smoked cheese looks amazing btw.

      I've had success fermenting at 20 (68f) here in my home. It typically takes about 3 days, but it can vary. Look for light orange/yellow coloring and use the smell as a good indicator. Andrea Nguyen suggests poking few holes in the plastic wrap, but otherwise the recipe is pretty similar.

      I love to spread this on home made sourdough and it is the secret ingredient in vegan mac and cheese as well as soy milk ramen. Lastly, I find the mix of gochugaru and szechuan peppercorns to be amazing.

          In the latest batch I'm creating, I've noticed a few pieces with white "hairs". It looks like the version of what is called hairy tofu. I didn't have this result in the previous 2 batches so I'm wondering if it is OK. I think it should be since it smells OK and there are no black spots. This is about at day 2 right as the orange tint is starting to develop. Any thoughts Thomas?

            As long as you don't have too much of this hairy mold it's okay. I also see some developing some times.

      Hi Thomas,
      Thanks for sharing your recipe and technique!
      I’ve been fermenting my tofu cubes for 3 weeks and the cubes are kind of breaking apart. Also on a few cubes there is a pinkish or purplish tinge...is this bad mold do you think?
      Thank you!

        Hi Kieran,
        You're welcome! Tofu cubes should be very very soft and could be mashed into a smooth cream, they should not break apart too easily though.
        Yes pink/purple mold is not good I'm afraid.

      Thank you! Do your readers know they can buy this, in jars, in Chinese grocery stores? If you buy it/taste it first, then you will (a) know whether you like it, (b) know what you are aiming for--what is good, and (c) what is a definite failure. (I personally think that is critical when you are trying to make something new. Especially with fermentation, the success of which will depend on what is in your air!) I have read that, in the factory where this is made in Hong Kong, they have a room that is full of the right kind of spores. They simply put racks of pressed tofu in this room for a few days, it ferments and they then bottle it. You can also taste this in some Chinese restaurants. The Taiwanese eat fermented tofu with porridge (congee). The Cantonese use it to cook certain dishes--water spinach, in particular. Actually, there are three kinds of fermented tofu: the white kind as described here; a dark red kind with a different flavor, and then a third kind that is only deep-fried in cubes--usually served as street food. You know whether the vendor is by the smell!

      Oh, yes, I’m going to make this recipe! I occasionally buy Chao from a Chinese guy at our local farmers’ market. I just eat it with gluten free toast, and I have to be quite economical with it because for a small amount I pay around $8.00 CAN. I absolutely love it. I’m unable to consume dairy products and this is really nice and cheesy. Stinky cheesy, in the most delicious way. Thanks for demystifying it. I’d Googled it a while ago and the recipe I found made me feel that I was bound to screw up and end up with something that could give me an upset stomach. Your recipe makes me feel that I have to dash out and buy firm tofu right now! Thanks 🙂

      Hi Thomas, thanks for the recipe! Have you ever tried fermenting okara? The reason I ask is that I cannot find good tofu where I live in rural France so I make it myself. As a result, I have some tofu and a lot of okara! I would be curious to know whether you actually experimented with this or not. Thanks in advance!

      I made this according to your recipe and I was so excited. I have heard that yellow and red moulds are bad? But the chunks developed the colour and some blue, which I scraped off before bottling... Also when I had left it in brine it developed some patches of green/blue mould on the top. I scooped it off and put sesame oil on it and refrigerated it. What do you think? Will me batch be okay?

        Yellow mold can appear on your tofu, it's not bad. However if you see some blue/green mold it's not good. I would start again.

      I haven't made this yet, but am wondering if you have to make a fresh batch each time, or whether you can just keep adding freshly cooked tofu to the rice wine mix, which I guess would be left over each time.

        September 04, 2020 at 7:29 pm

        That is a good question. In my opinion, yes you do have to make a fresh batch each time as each cube of tofu has to get some mold growing on it in order to ferment and become very soft.

      Ok so I made this recipe and I waited until today to open it up, and it’s delicious! It has a lovely creamy texture and deliciously deep, mature taste, very much like blue cheese. However, it’s incredibly salty, so I’m going to use it as part of other things, like creamy sauces and as a base for cashew cheeses. Can’t wait. Although saying that, it might just disappear on the back of some crackers, washed down by crispy cold white wine, accompanied with grapes and or figs.

      Thanks so much as ever, Thomas, for your creativity and generosity in sharing your epic recipes.

          Hi again,

          I made this again, and whereas the first time I used fresh tofu from the Chinese supermarket as you suggest, this time I used used ambient tofu, the kind you get in a cardboard rectangle that you don’t have to refrigerate, and it was creamier and softer but still delicious. I also put some liquid smoke and it tastes a-ma-zing. It was also less salty, somehow.

          Honestly, Thomas, this is a game-changer for me. Can’t thank you enough.

            Hi Elise,
            Usually the tofu sold in cardboard rectangles is silken tofu, so if that's the case it's not suitable for this recipe I'm afraid.
            Well, glad you still liked the result 🙂

      HI. Thank you for another great recipe. I just stored the jar in warm dark place.
      I had a problem to keep the tofu under the brine.due to the salt the tofu floated. I added oil trying to prevent the tofu exposed to the air that traped under the lid, but yet' some tofu is floating abuve the oil too.
      I hope it want spoil the Chao.
      Do you have an idea how to keep the tofu covered?

        Well usually the tofu will slightly float after a few weeks in the brine, but if your jars are full it should not float that much.

      Hi There,

      firstly, thanks for the great recipe!

      a question though, I fermented my tofu and after around 2 days I found it to have some hairy white mold on it. as well as the orange markings. The smell was not that bad to my nose, nothing worse than most stinky cheese, so,
      I have still used this tofu and put it into jars. it is fermenting quiet quickly and i have had to gas the jars after 2 days.

      my question though is whether you think I should discard this tofu in the prescience of the white hairy mold? I know that tofu is often fermented to become hairy, but I'm also aware that that could b a ore controlled process

      thanks again!

        Hi Timothy,
        You're welcome! White mold is okay and can happen. I had white mold many times and the chao tasted amazing even after over a year!
        What you should be careful about is pink and black mold.

      Thank you for this recipe,the Chao has a good flavour.I have used it for the slices of cheese & it was so tasty.
      I was wondering if it could be used instead of coconut oil in the vegan blue cheese recipe,?I was going to put in about 1/4 of a cup just to see how it affects the flavour,& setting quality
      My son liked the cheeses I make so much that he is now making them himself,your recipes for cheese are the best that I have tried.

        1/4 cup of chao seems a lot and I'm afraid your cheeses will be too salty. I would recommend using 2 tablespoons of chao, it should already give your cheeses a deeper flavor.
        I'm happy to hear your son enjoys the cheeses 🙂
