Beef tenderloin is a cut of beef that comes from the short loin. It is a long, narrow muscle that is very tender and flavorful. Beef tenderloin is often used for special occasion meals, such as steak dinners or roasts.
There are a few things to keep in mind when buying beef tenderloin. First, you want to make sure that the beef is fresh. The meat should be bright red and have a slight marbling of fat. Avoid any beef that is brown or has a lot of fat. Second, you want to choose a beef tenderloin that is the right size for your needs. Beef tenderloin is sold by the pound, so you will need to know how many people you are serving before you buy it. A good rule of thumb is to allow for about 1/2 pound of beef per person.
