2-1/2 pounds pork baby back ribs, cut into 8 pieces
5 cups water
1 medium onion, sliced
2 celery ribs, cut in half
2 teaspoons minced garlic, divided
1 teaspoon whole peppercorns
1/2 cup barbecue sauce
1/4 cup plum sauce
Dash hot pepper sauce
Place the ribs in a 5-qt. slow cooker. Add the water, onion, celery, 1 teaspoon garlic and peppercorns. Cover and cook on low for 6 hours, or until meat is tender.
In a small saucepan, combine the barbecue sauce, plum sauce, hot pepper sauce and remaining garlic. Cook and stir over medium heat for 5 minutes or until heated through. Remove ribs. Discard cooking juices and vegetables.
Brush ribs with sauce. Grill, covered, on an oiled rack over medium-low heat for 8-10 minutes or until browned, turning and basting occasionally with remaining sauce.
