Yes, the grill is a summertime icon, but a barbecue is more than an excuse for a backyard get-together.

1    tablespoon   packed brown sugar
1    tablespoon   paprika
1    teaspoon   garlic powder
1    teaspoon   celery salt
1/2   teaspoon   dry mustard

1    cup   ketchup
1/4   cup   molasses
1/4   cup   cider vinegar

2    tablespoons   brown sugar
1    tablespoon   chili powder
1    tablespoon   yellow mustard

directions
Preheat oven to 350 degrees F. Trim fat from ribs. Place ribs in a shallow roasting pan. For rub, in a small bowl stir together brown sugar, paprika, garlic powder, celery salt, dry mustard, black pepper, and cayenne pepper. Sprinkle rub evenly over both sides of ribs; rub in with your fingers. Cover pan with foil.
Bake ribs for 2 to 2-1/2 hours or until very tender. Carefully drain off fat in roasting pan.
For sauce, in a medium saucepan cook onion and garlic in hot butter over medium heat about 5 minutes or until tender. Stir in ketchup, molasses, vinegar, the water, brown sugar, chili powder, yellow mustard, Worcestershire sauce, and salt. Bring to boiling; reduce heat. Simmer for 20 to 25 minutes or until desired consistency.
For a charcoal grill, sprinkle the wood chips over the coals. Grill ribs on the rack of a covered grill directly over the coals for 10 to 15 minutes or until ribs are brown, turning once halfway through grilling and brushing occasionally with sauce. (For a gas grill, preheat grill. Reduce heat to medium. Add wood chips according to manufacturer's directions. Place ribs on grill rack over heat. Cover; grill as directed.) Serve ribs with remaining sauce.
Note
*Note:
For the most smoke production, soak wood chips in enough water to cover for at least 1 hour before grilling. Drain wood chips before using.
