This is the concluding article of my 3-part series on Milking The Soy Bean. In Part 1, I described how to make soy milk with no special equipment, and in Part 2 I showed how to make tofu. The by-product of turning soy beans into soy milk or tofu is the ground up fibrous part of the bean. This is called okara or, more quaintly u no hana (卯の花) in Japanese. (I don't know what the u part is, but hana means flower, so it's the u-flower.) Okara is a nutritional powerhouse, containing soluble and non-soluble fiber, protein, calcium and other minerals.
