Rub the spice mixture evenly on all sides of the ribs. Place the meat in a resealable plastic bag or a baking dish covered with plastic wrap and refrigerate for 8 hours or overnight. 2Let the ribs sit at room temperature for 1 hour before cooking. Heat a grill pan or outdoor grill to medium (about 350°F to 450°F). 3Place the ribs on the grill with the larger, flatter side down, cover the grill, and cook until the pork is browned and crusty on the bottom, about 5 to 7 minutes. Flip, cover, and cook until it’s browned and crusty on the other side, about 5 to 7 minutes more.
