Soy beans play an important role in Asian cooking. The beans themselves are used, as well as flour made from dried beans, tofu made from soybean curd and soy sauce made from fermented beans. As an interesting comparison, you might have a can of soy-based infant formula for children to taste alongside this homemade preparation.(Note: This will take a couple of days given the soaking time for the beans, so plan ahead. You also will need an electric blender and a cheesecloth bag or large piece of cheesecloth.)
