Clean the fish, seeing that all scales are removed. Stuff and sew. Shape with skewers to form a letter S and place upright on a baking pan or lay fish on side. If the fish is not a fat kind, put strips of salt pork over it and in pan or cut gashes in fish and lay strips of pork in them. Dredge with flour. Bake one hour for a three-pound fish, in a hot oven, basting frequently with the tried-out fat. Serve with drawn butter or Hollandaise sauce.
