Side-by-side
| heart | sirloin tip | |
|---|---|---|
| Primal | offal | round |
| Muscle / location | Chest cavity — between the lungs, behind the brisket | Front of the rear leg, between sirloin and round |
| Character | A dense, muscular organ with a mild, beefy flavour — closer to lean muscle meat than most offal. Often grilled on skewers (anticuchos in Peru) or braised. Very lean; benefits from marination. Widely eaten in Latin America, Eastern Europe, and across Asia. | Also called the knuckle. A lean, moderately tender cut from the front of the round, near the sirloin. Used for roasts, kabobs, and stir-fry. Not from the sirloin despite the name. |
Key differences
- Different primals: offal vs round.
- Texture and slicing: compare fibrous, grain-heavy cuts vs more tender steak-style muscles based on each cut’s description.
- Retail naming diverges by country—always map through a canonical cut when translating menus or labels.
