Beef chuck also known as ''Boneless Beef'' comes from around the shoulders and is often sold pre-diced to be used in certain dishes. It is a heavily exercised area. However, this area contains a great deal of connective tissue, including collagen. Collagen melts during cooking, making the meat intensely flavorful. Cuts from this area will benefit from slow, wet cooking methods like stewing, braising or pot-roasting.
