I usually cook pork chops at 250° until they hit 150°-160° on the pellet grill. I make them a few different ways:
1. Soak overnight in Lawry's Caribbean Jerk marinade
2. Soak overnight in Italian Dressing and Worcestershire
3. Use a rib rub overnight
Sometimes, I put nothing on them and smoke them until about 140°. Then we through them in a pan with crushed tomatoes, peppers, onions, mushrooms, garlic and simmer covered until fall apart tender.
