Step 1

Season the ribs with a light, even sprinkling of salt and plenty of black pepper. Rub the brown sugar over the entire surface of the ribs. Do not remove the membrane on the back.

Step 2

In your Instant Pot, pour in 1/2 cup apple cider vinegar and stand the ribs up in a half circle using the rack that the Instant Pot comes with. Cook on high pressure for 10 minutes, followed by 5 minutes of natural release. Next, carefully release the steam vent. Once the steam has completely released, open the pot and carefully transfer the ribs to a platter.

Step 3

Brush generously with barbecue sauce and either grill the ribs or bake them at 450 degrees F/230 degrees C for another 15-20 minutes, brushing every 3-5 minutes with additional barbecue sauce until caramelized.
