Boneless pork shoulder steaks work well because they contain some fat to keep the meat moist. However, because shoulder steaks contain different muscle groups the texture can change from bite to bite. Well-marbled pork chops with a little fat cap around the edge would work, too. If using bone-in chops, I would use 3 pounds rather than 2 ½ pounds. Be sure to use a good quality five spice powder.
