I buy organic regionally grown soybeans for about $1.39lb.
1. Soak 1 cup dried soy beans for 48 hours.
Makes about 4 cups milk and 1-2 cups moist pulp. Adding more water makes thinner milk, perfect for vegan cooking and baking; less water makes a creamier product, better for use as dairy-free coffee creamer, with cookies, over cold or hot cereal, as a base for non-dairy ice creams and making soy yogurts and vegan cheese.
Save the pulp (okara) for other recipes. I fermented mine.
