A pork chop is just a pork chop, right? Well, actually not. In fact, there are three different cuts of chops; the rib chop, the loin chop, and the sirloin chop. Each of the three cuts comes from the pork loin, which is the tender strip of meat that runs from the shoulder butt back to its leg (hip).
A whole bone-in pork loin contains the loin meat, the tenderloin, and the baby back ribs. Pork rib chops originate from the center of the loin. A layer of fat runs along the outside edge of the chop. Rib chops are relatively tender and juicy.
