Instant Pot Baby Back Ribs

• 4 lbs baby back ribs, (2 full racks)
• 1/3 cup pork dry rub*
• ¾ cup water
• ¾ cup apple cider vinegar½ tsp liquid smoke, optional
• 2 cups barbecue sauce

1. Working with one rack at a time, use a paring knife to separate the thin transparent membrane on the inside of the ribs. Peel it away from the ribs. It should come off in one big piece.
2. Rub the ribs well on all sides with dry rub. If possible, cover and let rest in the fridge overnight.
3. In the bottom of an Instant Pot, add some foil balls or a rack to raise the ribs above the liquid. 
4. Pour the water, vinegar, and liquid smoke into the instant pot.
5. Add the ribs, bending them to fit. 
6. Lock the pressure cooker and cook on High pressure for 30 minutes. 
7. Release the pressure naturally for 10 minutes, then vent off the remaining pressure.
8. Remove the ribs from the instant pot and spread them out on a baking sheet. 
9. Brush liberally with barbecue sauce, then broil on high heat for 5 minutes.
10. Slice ribs and serve with sides and extra sauce.
