In a saucepan, heat the soy milk to 110°. I make my own soy milk, but you can use a brand you purchase from the grocery store too.
4 cups Unsweetened, plain soy milk (purchased or my recipe)
Add probiotics. Use a packet or the contents of a pill. I’ve experiments with a few different probiotics and my go-to brand is NewRhythm Probiotics 50 Billion CFU which I get on Amazon. Probiotics are super healthy and give you vegan Greek yogurt the wonderful tangy flavor.
Curdle the milk. The yogurt maker keeps the soy milk heated at roughly 110° consistently and I suggest you leave it overnight so it can thicken and curdle. Curdling is actually a souring of the milk that creates clumps (curds). This is the reason your vegan Greek yogurt is tangy!
Transfer to you strainer. Once the soy milk has curdled overnight let it cool and transfer it to a strainer. I use the Euro Cuisine GY50 Greek Yogurt Maker and I love it! This is just perfect for making vegan Greek yogurt. I let this strain overnight and in the morning voilà you have your homemade vegan Greek yogurt.
