For most outdoor cooks, barbecued ribs occupy a place outside the typical comfort zone of hamburgers, steaks, and chops. The intricacies of slow-cooked, smoky barbecue seem shrouded in mystery. What with all the insanely complex spice rubs, glazes, and sauces, plus the vagaries of tending live fires, it's a cult better left to the pros, right?
Wrong! I'm here to open the doors to the inner sanctum of the barbecue world and show you how easy pork ribs can be. Your biggest obstacle is time. That's it. Just the time it takes for the rib meat to surrender its grisly texture and collapse into tender shreds of succulence beneath a slightly crisp and caramelized surface. If you've got time and an outdoor grill, you can barbecue great ribs.
Start by choosing your ribs. Pork is traditional for barbecuing, and the two most popular choices are baby backs and spareribs. Baby backs, also known as top loin or loin back ribs, are smaller (2 to 2-1/2 pounds per rack) and more expensive. They're cut "high on the hog," near the backbone, where pork chops and tenderloins come from, so they're usually more tender.
Spareribs are larger (4 to 5 pounds per rack, untrimmed) and less expensive. They come from the belly of the animal, close to the section that's turned into bacon. They're usually meatier, fattier, and more flavorful. I like to barbecue St. Louis-style spareribs, which are regular spareribs minus a few chewy odds and ends: the breastbones along the bottom, the pointed tops at one end, and a strip of scraggly meat dangling from the bone side. If your store has only regular spareribs, ask the butcher to trim them St. Louis-style for you.
