8 cups or 1/2 gallon of milk(soy, rice, almond or coconut!!)
1/2 cup plain soy yogurt OR 1/4 tsp probiotic
Use at least a 4qt crockpot.
Pour 1/2 gallon of milk into your crockpot and cook on low for 2 1/2 hours.
Turn off crockpot and let sit for 3 hours.
Take out 2 cups of the milk and stir in the yogurt or probiotics.
Return to crockpot and cover with heavy towel.
Let sit overnight!
Wake up in morning and have fresh, healthy, cheap, allergen-free, yummy yogurt! Puree in some frozen fruit or a large drizzle of maple syrup to sweeten it up. If you want it to be thicker whisk in 1/4 cup tapioca starch--it's what the pro's do!
