This is a whole USDA Prime beef loin tenderloin sold in a full case and priced per pound. Rated at the highest USDA quality grade, Prime beef is distinguished by its exceptional marbling, tenderness, and rich flavor. The "Extreme Peeled" (EXTM) designation means the tenderloin has been meticulously cleaned by professional butchers, with all silver skin, exterior fat, and tough connective tissue removed. The "Side Muscle Off" (SMO) designation indicates that the chain muscle (psoas minor) has been fully separated from the main tenderloin, leaving only the prized psoas major โ the most tender muscle on the animal.
Because all trimming work has already been completed, these tenderloins are ready to cut into filet mignon steaks, portion into chateaubriand roasts, or prepare as a whole roasted tenderloin for special occasions. Purchasing a full case at the per-pound price offers significant value compared to buying individual steaks. The extreme trim level also makes these cuts ideal for restaurant and foodservice use, where consistent, clean portions are essential.
