Pour 2 cups of ginger ale in pressure cooker.
Follow directions for your pressure cooker and fully cook the ribs. For mine it is 35 minutes on high.
Release pressure according to you pressure cooker instructions and remove ribs. Pour hot sauce over the hot ribs and allow them to soak in the sauce until ready to finish on the BBQ. (Can be a few hours to 2 days). You can also freeze the cooled ribs a this point for future.
When ready to serve heat BBQ and set to medium. Distribute ribs over the grill and allow to heat through, turning and moving so they don't burn. Serve once heated and sauce has caramelized,crisped a bit.
