MUSHROOMS WITH ONIONS
Peel 2 medium-sized onions and chop them fine, and put them in a casserole, or saucepan, with 1 tablespoon of melted butter. Let them cook slowly for ten minutes, then add 1 pound of mushrooms, which have been carefully washed or peeled, and another tablespoon of butter, and cover, letting cook for ten minutes. Season well with salt and pepper and serve very hot.
Mushrooms thus prepared may be put in a deep baking dish, covered with crust and baked in a pie.
