Boneless beef short ribs are a very flavorful cut that must be slow cooked (typically braised) in order to become tender. Having the bones removed makes them easier to cut, portion & shred than bone-in short ribs.
Short rib meat can also be smoked or slow roasted with very flavorful results, though it may be less tender.
This short rib meat is center cut from the short ribs running through the chuck & plate.
