Tender Only

The food you are referring to is likely "tenderloin," which is a cut of meat that is known for its tenderness. Tenderloin is a cut of beef that comes from the short loin of the cow, and it is typically one of the most expensive cuts of beef available. It is called "tenderloin" because of its tenderness - the muscle fibers in this cut of meat are thin and close together, which makes it very tender when cooked.

Tenderloin is a popular choice in restaurants in the United States, and it is often served as a steak. It can be grilled, broiled, or pan-seared, and it is typically served with a sauce or a compound butter to add flavor. Tenderloin is also a popular choice for special occasions, such as holidays or anniversaries, because of its rich, buttery flavor and its tenderness.

It is worth noting that while tenderloin is a popular choice in restaurants, it is also possible to find it at some grocery stores. If you are interested in trying tenderloin, you may be able to find it at a specialty grocery store or a butcher shop. Just keep in mind that it is a more expensive cut of meat, so it may be a bit more expensive than other cuts of beef.
