Side-by-side
| kidney | top round steak | |
|---|---|---|
| Primal | offal | round |
| Muscle / location | Lower back — lumbar region, embedded in suet | Steak cut from the inside round / top round |
| Character | Beef kidney has an intense, mineral flavour distinctive of the organ. Often sold trimmed of its surrounding suet (kidney fat) or with it attached. 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 lean, affordable steak cut from the inside round. Often marketed as 'London Broil' in US supermarkets, though London broil is technically a preparation method, not a cut. Best when marinated, grilled to medium-rare, and sliced very thin against the grain. Overcooking makes it tough and dry. |
