    Soy yogurt

    Sometimes we buy packaged food for convenience, and sometimes we believe that prepare them ourselves have to be difficult and expensive. This homemade soy yogurt is a clear example of how easy it can be to prepare food at home and in addition, we can save money.

    To make homemade soy yogurt you're gonna need only two ingredients: soy milk and a starter (you can use store-bought or previously homemade soy yogurt or a yogurt starter powder). So simple and cheap.

    Soy yogurt

    I used to buy organic soy yogurt and it was quite expensive, but now I only need homemade soy milk and a homemade yogurt. That's all!

    Soy yogurt

    You only need to buy a store-bought yogurt or a yogurt starter powder for the first time, then you can use your own homemade soy yogurt as a starter.

    You can also make homemade yogurt with others plant milks, we also make yogurt with coconut milk and a yogurt starter powder (we couldn't find coconut yogurt), it's really creamy, sweet and delicious.

    Soy yogurt

    We've used homemade soy milk, it's so cheap and easy to make, and it tastes so much better than store-bought, you should try! We'll share the recipe soon. Use not transgenic or genetically modified soy milk and with no additives, preservatives or sugar, you can add healthy sweeteners such as dates, stevia, coconut sugar, maple or agave syrup, etc.

    Soy yogurt

    We've used a teaspoon of agar agar powder for a thicker yogurt, but you can use other thickeners such as tapioca flour, carrageenan, corn starch or corn flour, xanthan gum, flax seed, etc. You can add more or less thickener, it depends on the consistency you want.

    Soy yogurt

    I have good news for you, you don't need any equipment, if you have an oven, you can make homemade yogurt! You only need to preheat the oven at 50 º C or 120 º F for a few minutes, turn off the oven and place the yogurt inside for about 8 hours.

    Soy yogurt

    You can add fruits, seeds and nuts to your yogurt, so it will be even healthier and more nutritious. This time we've added nuts, sesame seeds and goji berries, we love them!

    Soy yogurt

    We recommend you to make homemade soy yogurt, it's cheap and easy, and also it's healthy, creamy and it tastes amazing! If you don't like the soy flavor you can make homemade yogurt too, you only need your favorite plant milk and a yogurt starter powder and you'll make the best yogurt you can imagine. Seriously, it's awesome!

    Ingredients

    • 1 teaspoon agar agar powder
    • ½ cup soy yogurt, or yogurt starter powder (the amount may vary, follow the package instructions)

    • Preheat the oven at 50º C or 120º F.
    • Pour the soy milk in a saucepan, add the agar agar, stir and heat the mixture to 90º C or 195º F, but be careful because it shouldn't boil. You can use a thermometer, but it's not necessary.
    • Pour the mixture in a bowl and let it cool to 40 or 50ºC (105º F or 120º F). If you don't have a thermometer you can put your finger in the mixture and when it's hot but not burn it's ready.

      I just made my first soymilk yogurt (not using your recipe... but will next time!) The dorexctions with the maker were what we followed. Took 4 oz of soymilk and mixed with 2.4 oz of store bought soy yogurt and whisked. We then added it to 32 oz soymilk and stirred it, then put all of it (cold) in our new yogurt maker cups (that we sealed with their tops) turned it on and it sat for 10 hours and sadly most of it didn't set at all. The ones that did set are fizzy. Do you have any thoughts of what went wrong?

      Hi Iosune I made the yoghurt last night and was pleasantly surprised that it had set when I woke up but, it resembles more of a pannacotta texture rather than creamy yoghurt texture. Is that normal? Is there anyway of making it more creamy as I popped it in the blender and now it's more of a yoghurt drink 🙈
      Thank you x

      iosune! Have you used any homemade soy milk? I've been using the Westsoy plain soy milk with great results, but it costs about $3.49 for a box. I make my own soy milk to use for making tofu and vegan cheeses. I tried using it for yogurt and it was a failure. About half the Instant Pot was filled with whey. Let me know if you've had good luck using your own homemade soy milk. Thanks so much.

        Hey Stephen, I also bought that soy milk but it was the UHT type and it didn't set up--stayed watery, so I'm wondering if yours was also UHT and if that is affecting it.

          Hi Stacey,

          I've been making yoghurt for a few years now. I place it in my van throughout the day in summer as I have no oven. Over the colder months when I can't make yoghurt I store the starter in the freezer (you only need a small jar of it). The longer you use the same starter, the thicker the yoghurt.

          Yes! The vegan yogurt starters are expensive. I use one probiotic capsule in each batch plus 3/4 cup of the last batch I made. The one I use has 100 Billion Live cultures, 12 Probiotic strains.

        savanna, I got tired of buying the vegan yogurt starter because of the cost. Researched using probiotic capsules. What I use successfully is RenewLife Ultimate Flora Probiotic. It has 100 billion Live Cultures of 12 Probiotic Strains. I use an Instant Pot. Pour in one carton of soy milk, 1 heaping tablespoon of arrowroot, 1 teaspoon of agar powder, and then open one capsule into the mix and whisk it up good. I also keep about 2/3 cup of the last batch to add. I probably don't have to use the capsule if I do that, but the yogurt is so good I don't want to find out!

          Stephen, I think I will try that, sounds really good. I'm concerned about my yogurt not thickening up. I've made homemade vegan yogurt in the past that turned out too runny, so I think both the arrowroot and agar agar could really help thicken it up.

          Soy Yoghurt makeing. Hallo Stephen, I read your comments regarding the vegan yoghurt start kit. I am in South Africa, and I cannot even find a vegan starter kit. So, I have the organic soy milk, the agar agar. Cannot find the arrowroot, what is it used for, please? Also, the probiotic capsules that I have, has only 5 billion live cultures. Please be so kind as to advise. 1 want to make 1 litre of soy yoghurt.

          Ronelle! I'd go ahead and use the capsules you have. It's good to have a variety of cultures. Mine has 12. The arrowroot acts as a thickener. In cooking main dishes cornstarch can be substituted, but I've never read anywhere that it can be used to thicken yogurt.
          Xanthan gum can be used. It's tricky, tho, as it easily clumps up. If you have access to some, maybe put a cup of the soy milk in a sauce pan and slowly sprinkle some on top of the milk while whisking. Maybe for your first batch try 4 capsules of the probiotics. ALSO, 2/3 cup of a plain vegan yogurt could be used. HOWEVER, all vegan yogurts have all kinds of things in them to help bind and thicken the yogurt. Maybe it won't affect the outcome of yours. Make sure the soy milk you're using is only soybeans and water. As soon as you make a successful batch, put about 2/3 of a cup into a sealed container and keep it and use it as starter for the next patch. The yogurt will get thicker the first few times. All the best.

          Hello Stephen, hope this gets to you! I'm trying to get my yogurt to thicken up. It's very runny. I just made my first batch with agar. Still watery. 😕 Other recipes I've read say to heat the soy milk and agar, a time - consuming step I'd rather not do, if I don't have to. (I did that with this batch) Do you heat the agar or do you just put it in the IP with the soy milk and starter and go from there? Thanks for your help!

        • STEPHEN SINCLAIR says

          June 25, 2022 at 9:46 pm

          Leigh! I've also read things about agar agar needing to be heated up. I tried heating some with a cup of soy milk and then putting into the IP, but, as I recall, it either wouldn't mix in with the rest of the milk when I whisked it or it settled to the bottom. As I said above, my IP soy yogurt is perfect every time. I use a 32 oz box of soy milk that has nothing in it other than soy and water. (There are a few brands out there. Costco's are a great price.) I place it in the IP, add 3 heaping TBS of arrowroot, 3/4 cup of starter saved from the previous batch, then 2 tsps of agar agar. I whisk it up good. So, I really don't know if the agar agar is doing anything, but I don't want to experiment by leaving it out (Maybe I should try that.) Also, after the 8 hours, I use a big spoon to lift the firmest yogurt out and place it in my yogurt jar. Then the 3/4 cup for the next week. After that I take a nylon nut bag and pour the rest of the yogurt into it. (There's a bit of liquid.) I use the strings to hang it on my kitchen faucet while placing a mixing bowl beneath it. Within an hour or so much of the liquid is out of the bag. The longer it hangs the more "Greek yogurt-like" it becomes. I then use a spatula to get all the thick yogurt out of the bag and place that on top of the yogurt already in the jar. When I use it for breakfast along with walnuts and fresh fruit I spoon some of both the consistencies into the bowl. Hope that help!

        I believe there's something about the heat on a slow cooker being too high to make yogurt. I use my Instant Pot and get perfect yogurt every time. (There's a yogurt setting that sets and maintains the right temperature for 8 hours.) I use agar agar and arrowroot for thickeners.

      Hi! I made this, but used a mix of almond and soy milk, used soy yoghurt as a starter and added some erythritol for sweetness. I left it in the oven at 35 degrees c. When I came back to get it out, there had come a brown film/crust on the yoghurts and it stank so bad. I removed the film and gave it a stir. It was quite liquidy, but didn't smell nor have any brown tint to it. What did I do wrong? Is it still edible? Thanks.

          I did a batch this week end. I used 1/2 pint mason jars, Sous Vide at 110 F. for 24 hours, could probably shorten the bath time as the yogurt seemed to be firm set at around 12 to 14 hours. The yogurt set hard much like a Greek yogurt. I did not add any sweetener or vanilla as I wanted to compare the taste to a plain dairy yogurt. This seems to be a bit tartar than commercial yogurt but brightened up with a bit of honey.

          Thank you very much if you answer!

          Mathi,
          As noted in my original comment I used my Sous Vide immersion circulator (the temp lock thingy). Yes it is important to maintain temperature control when making yogurt as you are growing a live culture. Lack of temperature control could introduce unwanted bacteria to the mix.
