4 racks baby back ribs
1 1/2 cups water
1 cup white vinegar
1/2 cup tomato paste
2/3 cup dark brown sugar
1 tablespoon yellow mustard
1 1/2 teaspoons salt
1 teaspoon liquid smoke hickory flavor
1/2 teaspoon onion powder
1/4 teaspoon garlic powder
1/4 teaspoon paprika
Sauce: Combine all ingredients except ribs over medium heat. Bring to a boil; reduce heat and simmer, stirring often 45-60 minutes until thick.
Preheat oven to 300 degrees F.
Brush sauce over entire surface of each rack of ribs. Wrap each rack tightly in aluminum foil. Arrange packets on baking sheet with foil seam up. Bake 2 to 2 1/2 hours until the meat has pulled back from the cut ends of the bones about 1/2 inch.
Preheat grill to medium heat.
Remove ribs from foil. Grill on BBQ 4-8 minutes per side. Brush sauce on both sides a few minutes before removing from grill.
ENJOY!
