These Instant Pot Ribs are the most tender and fall-off-the-bone baby back ribs, rubbed in spices and cooked in your pressure cooker. Finish them off on the grill or under the broiler for the best ribs ever!
Prepare the ribs: remove membrane from the back of the rack (a thin film) by inserting a fork or knife underneath it and loosening up, then pull the membrane off and discard. Trim off any excess fat of the ends of the rack. Cut the ribs rack into 3 equal pieces.
Pour water, juice, vinegar and liquid smoke (if using) into the insert and stir.
