From: "Whole Grains Every Day, Every Way" by Lorna Sass. "The savory combination of buckwheat and cottage cheese shows up in many traditional Russian cookbooks, and creates the kind of dense, comforting pudding that we yearn for when there's frost on the windows. Use toasted buckwheat (kasha) for a robust flavor, and untoasted buckwheat for a subtler dish. Serve the casserole as an accompaniment to brisket, pot roast, or short ribs. Vegetarians will enjoy it as an entree."
