To prepare oven-roasted jerk pork leg, core the pork leg and rub it with wet jerk seasoning, dry jerk seasoning, garlic powder, apple cider vinegar, and pimento seeds. Marinate in the refrigerator for one week. Before roasting, bring the pork to room temperature. Roast in a 375°F oven for 3-4 hours, basting regularly with jerk seasoning. Once cooked, slice the leg and serve with jerk sauce, rice and peas, or ground provisions and dumplings.
