Vegan Yogurt

unsweetened soy milk carton (946 ml/ 32 oz/ 4½ cups)

vegan probiotic capsule (I use the 100 billion Ultimate Flora Ultra Potent in this recipe but any strong vegan probiotic that needs to be kept in the fridge will work). You use the inside powder of the probiotic in the recipe.

candy thermometer - this is to make sure your milk is at precisely the right temperature.
