Separate the racks into 3-rib sections and cover Cowboy Dry Rub seasoning. Insert the 2-piece rack into the CanCooker and coat the inside with non-stick cooking spray. Add the ribs and soda. Latch the lid and heat on medium low, steaming for 30 minutes. Remove from heat and let sit for 10 minutes. Transfer ribs to a tray and baste with BBQ sauce. Finish the ribs on a preheated grill and cook for 6 to 7 minutes per side.
