Description
Precision separation of the diaphragm's central tendon reveals a uniquely textured, flavor-concentrated steak.
Technical
Involves identifying and following the grain direction through the diaphragm muscle's connective tissue matrix, requiring specific blade angles to preserve the distinct longitudinal fiber structure.
Culinary Significance
Yields a cut with exceptional beefiness due to high myoglobin content and working muscle composition, prized for both tenderness and chew when cut correctly.
