• Rub the ribs with the spice rub on all sides. Let the ribs sit while you prepare the pressure cooker.
• Add the apple juice, liquid smoke, and apple cider vinegar to the inner liner pot of the pressure cooker. Place the metal trivet/rack in the pot.
• Place the ribs on the trivet, trying not to overlap by much.
• Place the lid on the pot and set the steam release knob to the Sealing position. Then press the Pressure Cook/Manual button or dial, then the +/- button or dial to select 25 minutes.
• When the cook time is finished, let the pot sit undisturbed for 10 minutes (10 minute Natural Release). After that 10 minutes, immediately release the remaining steam/pressure manually (avoids overcooking the ribs).
• When the pin in the lid drops down, open the lid.
• Use tongs to remove the ribs to a foil lined baking pan. Slather barbecue sauce all over them. 

Broil to Finish (optional step)

• Set the oven broiler to 350° - 400° F to start heating it up.
• Place ribs under the broiler for a few minutes to caramelize the sauce (this step is optional. Sometimes I just sauce them up and eat them). Watch them carefully to make sure they don't burn or get dried out.
• Serve with a little extra bbq sauce for dipping.
