Make a Brown Sauce of the fat, salt, pepper, flour, onion or parsley, and milk or stock. Mix with the meat. Butter the crumbs, and place about one half cupful in the bottom of the buttered baking-dish. Add the meat mixture, and cover the top with the remainder of the crumbs. Bake in the oven until the mixture is thoroughly heated and the crumbs are brown.
Cold fish may be shredded and used in the same way.
