Mix together the salt through allspice. Coat each pork chop with the rub, covering both sides generously. Reserve any leftover rub for a future use. Place the pork chops in a plastic food storage bag and refrigerate for 8 hours.
To cook the pork chops, remove them from the refrigerator and allow to come to room temperature, about 30 minutes. Preheat the oven to 350 degrees F.
In a large ovenproof skillet, heat the vegetable oil over medium-low heat. Add the pork chops, and cook on each side for 5 minutes. Place the skillet in the oven and cook the pork chops for 15 minutes, uncovered, or until a meat thermometer reads 145 degrees F. Allow to rest for 10 minutes before serving (there will be carry-over cooking).
