Kama (in Estonian) or talkkuna (in Finnish) is a traditional Estonian and Finnish finely milled flour mixture. The kama or talkkuna powder is a mixture of roasted barley, rye, oat and pea flour. The oat flour may be completely replaced by wheat flour, or kibbled black beans may be added to the mixture. Historically kama was a non-perishable, easy-to-carry food that could be quickly fashioned into a stomach-filling snack by rolling it into butter or lard; it didn't require baking, as it was already roasted.
