For a potent spice flavor, brine and dry the ribs as directed, then coat them with the spice rub, wrap tightly in plastic, and refrigerate overnight before grilling. You will need two wood chunks, each about the size of a lemon, for this recipe.
RECIPE INGREDIENTS For the Brine:
DIRECTIONS
TO BRINE THE RIBS:While ribs are brining, cover two 3-inch wood chunks with water in medium bowl; soak wood chunks for 1 hour, then drain and set aside. Combine spice rub ingredients in small bowl. When ribs are out of brine and dried, rub each side of racks with 1 tablespoon spice rub; refrigerate racks 30 minutes.
TO BARBECUE THE RIBS:Arrange ribs on cool side of grill parallel to fire; cover, positioning lid so that vents are opposite wood chunks to draw smoke through grill (grill temperature should register about 350 degrees on grill thermometer, but will soon start dropping). Cook for 2 hours, until grill temperature drops to about 250 degrees, flipping rib racks, switching their position so that rack that was nearest fire is on outside, and turning racks 180 degrees every 30 minutes; add 10 fresh briquettes to pile of coals. Continue to cook (grill temperature should register 275 to 300 degrees on grill thermometer), flipping, switching, and rotating ribs every 30 minutes, until meat easily pulls away from bone, 1 1/2 to 2 hours longer. Transfer ribs to cutting board, then cut between bones to separate ribs; serve.
