A porterhouse steak is a large cut of beef that comes from the rear end of the short loin section of a cow. It is known for its distinctive T-shaped bone, which separates two different types of meat: the tenderloin and the strip steak. This cut is prized for its rich flavor and tenderness, making it a popular choice for grilling and special occasions. Typically, a porterhouse steak is at least 1.25 inches thick and can weigh between 2 to 3 pounds. It is often served as a single steak for sharing, making it a favorite in steakhouses. When cooked properly, it offers a juicy and satisfying dining experience.
