One of the most impressive cuts of meat for the barbecue is beef back ribs, sometimes labeled as dinosaur ribs or dino bones because of their size. They're the rack of ribs that's cut away from a prime rib roast to turn it into a boneless ribeye, and they have a remarkably rich beefy flavor. Unfortunately, even though they're cut from the tender ribeye, the meat between the bones is tough and chewy. Slow-cooking them on your barbecue is one way to make them tender and give them a pleasantly smoky flavor.

Place the rack of beef ribs on your cutting board with the hollow of their curve facing upward. Unless your butcher removed it for you, the back will be covered by a thick, creamy-colored sheet of membrane. Use the tip of a knife to lever part of this membrane away from the ribs, then grasp it firmly with your hand and pull the whole sheet away.

Cut the rack into individual ribs or serving portions of two to three ribs each. You can cook the whole rack as one piece, but it's much easier to handle in smaller portions and more of the meat is exposed to the flavor-generating smoke and flame of the barbecue.

Rub the surface of the ribs thoroughly with your favorite dry spice rub or spice paste. Let them rest for at least 30 minutes and as long as overnight in your refrigerator, so the spices can adhere properly to the meat and begin to infuse flavors into the beef.

Light a bed of coals in your kettle and adjust the vents until they're burning evenly but gently. Move the coals to one side of the kettle, adding a few pieces of hardwood for smoke if you wish. If you're using a gas grill, light the side burners but leave the middle turned off. Wrap your hardwood chunks in heavy foil, then pierce the wrapper a few times with a skewer. Place this over one of the lit burners.

Position the ribs evenly over the unlit section of the grill, where they'll be gently cooked by indirect heat from the coals or gas flame. Close the lid. Adjust the vent and draft of your charcoal kettle, or the flame of your gas grill, until it reaches a stable temperature of approximately 225 to 250 degrees Fahrenheit.

Slow cook the ribs at that temperature for 3 to 4 hours, until the meat is tender and pulls easily away from the bone when tested with a fork.

Glaze the ribs, if you wish, by brushing them with a sauce or glaze. Then, open the vents on your charcoal grill or turn your gas grill to high. Finish the ribs for a few minutes at this temperature, until the glaze bubbles and caramelizes.

Transfer the ribs to a serving platter and serve them with your choice of side dishes.
