Best Barbecue Ribs - cooking recipe

Ingredients

2 tablespoons paprika
1 tablespoon brown sugar
2 teaspoons salt
2 teaspoons chili powder
1 1/2 teaspoons fresh coarse ground black pepper
1 teaspoon cumin
1/4 teaspoon cayenne pepper
4 racks of baby-back pork ribs (about 1 lb each)
heavy-duty aluminum foil
6 ice cubes

Preparation

Combine paprika, brown sugar, salt, chili powder, black pepper, cumin, and cayenne in a small bowl.
Pat ribs dry with paper towels.
Rub spice mixture all over ribs.
Place 2 rib racks side by side on a double layer of foil; place 3 ice cubes under the sides and seal foil around the ribs well.
Repeat with the next two racks of ribs.
Place foil packets on grill rack; cover and cook for 1 hour, carefully turning once with tongs after half an hour.
When ribs are done, cut an X in the top of the packets to allow steam to escape; pull foil back exposing the ribs.
Remove the ribs and place directly on the grill rack; cover and grill 7 to 10 minutes or until browned, turning once.
Brush ribs with barbecue sauce and cook 7 to 10 minutes longer, brushing with more sauce and turning often.
Cut ribs into 1-rib portions.
