WHITEFISH À LA CRÈME—I
Cook the fish until done in boiling salted water, drain, and remove the large bones. Cook together two tablespoonfuls each of butter and flour, add two cupfuls of milk, and cook until thick, stirring constantly. Season with salt, pepper, grated onion, minced parsley, and grated nutmeg, take from the fire and add half a cupful of butter. Add also the white of an egg well-beaten. Put the fish on a serving-dish, spread the sauce over it and brown in the oven.
