Side-by-side
| inside skirt | tongue | |
|---|---|---|
| Primal | plate | offal |
| Muscle / location | Transversus abdominis muscle — the inner diaphragm muscle | Head — muscular organ extending from the mouth |
| 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 tongue is a large, smooth-muscle organ prized for its tender, gelatinous texture when slow-braised. Widely eaten across Latin America, Europe, Japan, and South Asia — typically pickled, braised, or sliced and fried. One of the most flavourful offal cuts. |
