Set your Grilla, Silverbac or Kong to 250 degrees. Apply a base coat of rub to both sides of the rack. Place ribs on the grill and apply more rub as needed. Spritz ribs with either water or apple juice every 30 minutes to keep ribs moist.
10 minutes before your preferred doneness, you have the option to sauce the rack of ribs. Average cook time is about 4 to 5 hours.
