Side-by-side
| back ribs | inside skirt | |
|---|---|---|
| Primal | rib | plate |
| Muscle / location | Upper rib bones (dorsal side), removed from the ribeye | Transversus abdominis muscle — the inner diaphragm muscle |
| Character | The curved rib bones left after the ribeye is removed. Less meaty than short ribs but tender and flavorful. Popular in American BBQ (baby back ribs are pork; beef back ribs are larger). | 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. |
