What is the size of the Porterhouse steak?

The Porterhouse steak is a specific cut that is known for its considerable size and is typically larger than other cuts like the T-bone. It contains both the tenderloin on one side and the strip steak on the other, separated by a T-shaped bone. The average Porterhouse steak usually weighs around 22 ounces, which means that it is indeed the larger of the steak options presented.

This substantial size is why the correct answer is 22 ounces, as it represents the typical and expected serving size for a Porterhouse steak, which makes it not just a meal but an experience due to its size and quality. Understanding this cut's characteristics helps clarify why it stands apart in the world of premium steaks, often being served in steakhouse settings where generous portions are desirable. Other choices like 16, 18, and 20 ounces are indeed substantial, but they do not reflect the standard size associated with a Porterhouse steak.
