| Primal | plate | offal |

| Character | The 'other' skirt steak. Thinner, wider, and slightly tougher than the outside skirt (which is the standard 'skirt steak'). Most restaurant fajitas use inside skirt because the outside skirt is exported or sold at premium. Requires high heat, fast cooking, and slicing against the grain. | 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. |
