Quick Answer

Used in steak-and-kidney pie (UK), grilled whole, or sliced and sautéed. Requires the central white core (ureter) to be removed before cooking. | A triangular cut from the bottom sirloin (tensor fasciae latae muscle). Popularized by Santa Maria-style California BBQ. Lean with a pronounced grain that changes direction. Best grilled whole to medium-rare and sliced against the grain. |

- Different primals: offal vs sirloin.
- 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.
