Beef tenderloin (also called beef show) is the best choice for sauce beef. Tendrils are tight, and there is even fascia distribution in the meat, so it is easier to maintain the toughness and texture of the meat when cooking. When it is mature, the section of beef tendon will present beautiful and transparent marble texture, which increases the texture and beauty of meat. The circular arc of beef tendon meat is very suitable for the setting of cold dishes, which makes the sauce beef more attractive visually.
