What is the exact anatomical difference between a Porterhouse and a T-Bone steak?

Both steaks are cut from the short loin (NAMP 174) and feature a T-shaped lumbar vertebra separating the Longissimus dorsi and Psoas major. Per USDA standards, a Porterhouse must have a tenderloin diameter of at least 1.25 inches, while a T-Bone has a tenderloin diameter between 0.5 and 1.24 inches.

How many Porterhouse and T-Bone steaks are in a whole short loin?

A standard 24-pound short loin sliced to a 1.5-inch thickness typically yields 5 to 6 Porterhouse steaks, 6 to 7 T-Bone steaks, and 1 to 2 Club/13th rib steaks.

What percentage of a beef short loin is bone and fat tare?

Bone tare (chine bone and transverse processes) accounts for roughly 20% to 22% of total weight, while kidney knob suet, flank tail trim, and excess surface fat account for approximately 10% to 14%, leaving a net usable steak yield of 64% to 68%.

Why does the tenderloin side cook faster than the strip side in a T-Bone or Porterhouse steak?

The Psoas major (tenderloin) has lower intramuscular fat and higher water content with less thermal mass than the Longissimus dorsi (strip). When grilling, position the larger strip eye closer to the primary heat source while keeping the delicate tenderloin toward the indirect cooler zone.

Is it more profitable for a butcher to sell bone-in Porterhouse steaks or boneless NY Strip + Filet Mignon?

Fabricating boneless NY Strips and Filets removes the 21% bone tare, requiring higher retail prices per pound to offset the yield loss. In butcher shops, bone-in Porterhouse fabrication provides higher overall carcass profit while offering customers the iconic bone presentation.

What is a Club Steak and where is it located on the short loin?

A Club Steak (NAMP 1173) is the very first steak cut from the anterior rib end (13th rib) of the short loin after the tenderloin has tapered away completely. It is essentially a bone-in NY Strip steak attached to the L1 vertebra and 13th rib head.
