Boiling ribs, never! Barbecued ribs should be cooked slow on the grill. Whenever I turn the ribs over on the grill I spray them with water seasoned with vinegar, pepper, salt, garlic, and ground celery seeds. These moist, tender ribs are served with BBQ sauce on the side. These are well worth the time it takes them to cook. Boiled ribs aren't even in the same class.
