ESCALLOPED HALIBUT AU PARMESAN
Cut in thin slices four pounds of halibut meat. Put into a buttered pan with salt, pepper, grated nutmeg, and chopped onions to season. Cover, cook slowly, and then drain. Cook together two tablespoonfuls each of butter and flour, add a quart of milk and cook until thick, stirring constantly. Take from the fire, add the yolks of four eggs well beaten and half a cupful of grated cheese. Put into a buttered baking-dish a layer of fish, cover it with sauce, and repeat until the dish is full, having sauce on top. Sprinkle thickly with crumbs and grated cheese, dot with butter, and bake in a moderate oven.
