Place a double layer of some big sheets of heavy-duty aluminum foil next to the grill and place the ribs on the foil, meaty-side up. Wrap the ribs, sealing the package tightly. Place the foil-wrapped ribs on the grill for 1 hour. ☞ TESTER TIP: Wrapping the ribs in foil is essential to get them tender so don't omit this step. If you're planning to add that half cup of strongly brewed coffee to the ribs, this is the time to do it.
