Sweet-and-Smoky Baby Back Ribs with Bourbon Barbecue Sauce

To make these slow-cooked ribs, the barbecue is used like a smoker. The instructions given here are for a standard 22 1/2-inch Weber kettle barbecue. Grilling times and vent adjustments will vary with different brands of barbecues, and it may be necessary to cut the rib racks into four- or five-rib portions so that they’ll all fit on the grill. The only special equipment needed is a charcoal chimney, which is available at most home and garden stores and hardware stores.
