1/2 cup white vinegar
1/2 cup water
2 racks pork baby back ribs (about 5 pounds)
3 tablespoons smoked paprika
2 tablespoons brown sugar
2 teaspoons salt
2 teaspoons coarsely ground pepper
1 teaspoon garlic powder
1 teaspoon onion powder
1 teaspoon ground cumin
1 teaspoon ground mustard
1 teaspoon dried thyme
1 teaspoon dried oregano
1 teaspoon celery salt
3/4 teaspoon cayenne pepper
Combine vinegar and water; brush over ribs. Pour remaining vinegar mixture into a 6-qt. slow cooker. Mix together remaining ingredients. Sprinkle ribs with half the seasoning blend; reserve the other half. Cut the ribs into serving-sized pieces; transfer to slow cooker.
Cook, covered, on low until tender, 5-6 hours. Remove ribs; skim fat from cooking juices. Using a clean brush, brush ribs generously with skimmed cooking juices; sprinkle with reserved seasoning mixture. Serve ribs with remaining juices.
