| Character | A modern butchery innovation — the denver steak was 'discovered' in 2009 by meat scientists at the University of Nebraska. Extracted from the serratus ventralis muscle in the chuck, it's surprisingly tender and well-marbled for a chuck cut. An affordable alternative to ribeye with similar marbling patterns. | 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. |
