| 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 second most tender muscle on the entire animal, after the tenderloin. A flat, rectangular steak extracted from the top blade by splitting it along the central connective tissue. Uniform thickness makes it ideal for grilling. Also known as butler's steak in the UK. |
