Well, I think the title says it all! "Cooking with Heart and Soul", a cookbook by legendary singer and actor Isaac Hayes (Shaft?). Soul food, an often forgotten about, yummy, wonderful food, just because we may live way east of the Mississippi. Or, at least I do. Some of the beans may be hard to locate, there again, another reason we may not tackle some recipes. Just use what you can readily find. Wow! Another thought: wouldn't this look fabulous layered in a tall bottle? If you forget to soak the beans overnight, or don't have time to, just cover the beans with water, add a chopped onion, bring it to a boil in a stock pot or a dutch oven, let boil 2-4 minutes. Take off the heat, let the beans just sit for an hour. Drain, add fresh water just to cover them, and proceed with the rest of the ingredients.
Times will vary, depending on which method you choose. Time noted is for the overnight- soaking method. Note: adzuki beans can be found in Oriental markets. Hato mugi is actually a type of grain, and resembles barley, but isn't barley.
