Side-by-side
| skin | top sirloin | |
|---|---|---|
| Primal | offal | sirloin |
| Muscle / location | Outer hide — whole-body surface | Upper hip, above the sirloin cap (coulotte) and behind the short loin |
| Character | Beef hide/skin, sold cleaned and processed. Boiled to a gelatinous softness (ponmo/kpomo in Nigeria) or dried then rehydrated (cham in Arunachal, un in Manipur). Very high collagen; adds sticky body to stews. Culturally significant as a protein extender and a prized cut in West and Northeast African and Indian traditions. | A large, lean cut from the hip section. The top sirloin butt (NAMP 184) is the main muscle group. Versatile — grilled as steaks, roasted whole, or cut into kabobs. Moderate tenderness with good beefy flavor. Not to be confused with sirloin cap (coulotte/picanha) which sits on top of it. |

- Different primals: offal vs sirloin.
