The Steakhouse Hierarchy: How Chain Menus Are Handling T-Bone and Porterhouse Cuts
By David Miller
Every T-bone and porterhouse starts inside the short loin subprimal cut, located directly behind the animal’s rib cage and forward of the sirloin. This structural section contains two entirely distinct muscle groups separated by bone. On the larger side sits the longissimus dorsi, commercially sold off the bone as a New York strip. On the smaller interior side rests the psoas major, universally prized as the filet mignon portion.
The bone holding them together is a cross-section of the bovine T-shaped lumbar vertebra. The central stem of the "T" is the transverse process, flanked by the spinal canal ridge. This bone serves as far more than a decorative butcher handle. During thermal convection, the dense calcified structure conducts heat at a slower pace than the surrounding muscle tissue. The meat immediately clinging to the bone stays roughly 5°F to 8°F cooler than the exterior edges during high-heat broiling, creating a tender, moisture-retaining pocket that butchers refer to as the sweet cut.
Because the psoas major tapers naturally as it moves toward the front of the steer, its cross-sectional area changes with every cut of the butcher’s saw. Slices taken from the anterior end near the ribs yield a modest medallion of tenderloin. Slices taken from the posterior end near the hip feature a wide, rounded tenderloin mass. That single structural shift dictates which label appears on the restaurant receipt.
