Casserole of Mutton

• 1½ lb. middle neck of mutton
• 1 onion
• good gravy or stock

Cut the meat into neat chops and remove the bones and surplus fat. Place the meat in a casserole so that it is about half full. Thinly slice the onion and place on top and barely cover with gravy or stock. Season carefully. Cover and cook gently in a moderate oven (350° F., Gas 4), for about 1½ hr. Roll the suet pastry to the shape of the casserole—but slightly smaller. Lay the pastry on
