Okara is the pulp left over from soybeans after the beans are pressed for soy milk.
The pulp is white, and looks like wet, clumped sawdust, with no flavour to speak of.
In Asia, most of it is used for livestock feed. A small amount of it is eaten by humans, increasing in times of food shortages. There are, though, a few dishes made with it. In Japan, "Unohana-iri" is Okara that is sautéed with diced vegetables, then simmered in a broth and served over rice.
For Western recipes, Okara can be added in small portions to baked goods for added nutrition.
Okara should be cooked before adding to bread recipes; the enzymes in the raw bean pulp will interfere with yeast rising.

1/2 cup Okara = 2 oz / 60g
