|---|---|---|
| Primal | chuck | plate |
| Muscle / location | 5th rib, where the chuck meets the rib primal | Transversus abdominis muscle — the inner diaphragm muscle |
| Character | The 'poor man's ribeye' — cut from the 5th rib, right where the chuck primal ends and the rib primal begins. Contains the same longissimus dorsi muscle as a ribeye but from a less premium section. Similar marbling at a significantly lower price point. Only 2 steaks per animal from this location. | 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. |
