If you avoid wheat and you haven't tried it before, you should. It's a delicious alternative to rice or other cooked grains, with a nutty flavor all its own. Polish folks have a gazillion recipes for it, and some involve putting the kasha to bed. Yes, literally, putting it under the covers for a period of an hour or more.
I followed these directions here and merged with some other suggestions & recipes I found on the web. The result was delicious.
I used the above directions for toasting, precooking, and baking the kasha as suggested, but mixed the precooked kasha with a sauteed mushroom mixture before I put it in the oven. The mixture:
3 leeks, thoroughly cleaned then chopped (just the white parts)
1 pound brown mushrooms, chopped
dash of dry dill and thyme
fresh-ground black pepper
Saute in olive oil with some butter. Mix with pre-cooked buckwheat groats (3/4 cup kasha, toasted and tossed with melted butter) and a bit over a cup of water, cooked on low flame until the water evaporates) and 1 slightly beaten egg. Bake in 350 degree oven for about half an hour.
Would be delicious paired with a meat or dairy main dish.
