A mixture of cooked meat, chopped fine, and bound together with potatoes, breadcrumb and egg, or other binding material spiced and reheated. Usually shaped round or oval, and rolled in breadcrumb before cooking. Certain shapes, formed like rib chops, and with a piece of macaroni in each to represent the bone are designated cutlets; thus chicken cutlets, fish cutlets, &c.
