Dry the ribs with a paper towel, then remove the thin membrane from the back of the ribs.
Cut ribs cut into 3 bone pieces. Add rough chopped vegetables to the pot and place rack in the bottom of the Instant Pot. Add broth or water and set ribs upright on the rack.
Close lid and select manual pressure and set the timer for 23 minutes. Let the Instant Pot vent for 5 minutes and release the rest of the pressure. Take care of the steam, don’t burn yourself.
Brush with barbecue sauce and broil or grill until slightly charred.
I like to have the butcher cut the ribs down the center to create ‘riblets’.
