What type of meat is NOT part of the Porter House?

The correct answer is that Prime Rib is not part of the Porterhouse steak. The Porterhouse is a cut of beef that comes from the rear of the short loin and includes two primary sections: the tenderloin (or filet) and the strip steak (or NY Strip). This combination of meat provides both tenderness and flavor, making the Porterhouse a popular choice.

In contrast, Prime Rib refers to a different cut that comes from the rib section of the cow and is typically served as a thicker roast. It is primarily known for its juiciness and rich flavor, often cooked as a whole roast rather than cut into individual steaks like the Porterhouse. Since Prime Rib does not share the same anatomical source as the Porterhouse, it is not included in that cut of meat.

The other options, such as Filet, NY Strip, and Rib Eye, all pertain to cuts that can be associated with the general region where Porterhouse steaks are sourced, and thus they do not represent a distinct category that is separate from Porterhouse.
