Prime rib意思

"Prime rib" is a cut of beef that comes from the rib section of the cow. Specifically, it refers to the rib roast that includes the ribeye muscle, which is a particularly tender and flavorful part of the animal. The term "prime" in this context refers to the highest grade of beef as classified by the United States Department of Agriculture (USDA), indicating that the meat is of the highest quality with respect to marbling (the distribution of fat within the muscle), tenderness, and flavor.

When you see "prime rib" on a menu, it typically means that the rib roast is from a cow that has been graded "Prime" by the USDA. This grade is given to beef from young, well-fed cattle that have a lot of marbling, which results in a juicy and tender steak when cooked.

Prime rib is a popular menu item in many steakhouses and is often served as a roast, either whole or sliced into individual portions. It is typically cooked using a dry heat method, such as roasting, grilling, or broiling, and is often served with au jus or horseradish sauce.

It's worth noting that the term "prime rib" is most commonly used in the United States. In other countries, including the United Kingdom, the same cut of meat might be referred to as "ribeye" or "rib steak" if it is boneless, or "rib roast" if it includes the bone. The quality grading system may also differ in other countries.
