When beef heart is available (usually at better grocery stores or in butcher shops) it is usually already slit and cleaned, but it is necessary to cut away the fibrous outer covering. Reminiscent of steak, beef heart is ordorless and easy to work with. If beef heart is unavailable, or if you choose to substitute, most other meat varieties can be used (ground lamb, tripe, kidney, frankfurters, or cooked and ground turkey, pork or game meat).
