Mustard Glazed Ribs

1 rack pork ribs, cut into individual ribs, about 3 pounds

1 1/4 cups ketchup
1/3 cup cider vinegar
3 tablespoons spicy brown mustard
2 tablespoons brown sugar
3 tablespoons water
1 teaspoon onion powder
1/4 teaspoon hot sauce

3. Heat gas grill to medium-high or prepare charcoal grill with medium-hot coals. Lightly coat grill rack with oil or nonstick cooking spray.
4. Baste ribs generously with the remaining sauce and grill for 3 to 4 minutes per side or until nicely browned. Serve ribs with reserved sauce on the side.

Do ahead tip: Bake ribs and make sauce; allow both to cool to room temperature. Cover and refrigerate for up to 2 days. Gently reheat ribs and sauce before grilling.
