Cut the rack of ribs into 3 equal sections, then pat the ribs dry with paper towels. Rub and press the spice rub generously over each section of the ribs, pressing the spices into the ribs.

Place the metal rack into the bottom of the Instant Pot. Add the broth or water to the Instant Pot.

Place the ribs on the rack and arrange the ribs into a pyramid by standing each section up on its end and leaning them against one another.

Place the lid on the Instant Pot and lock it into place. Flip the valve to the ‘Sealing’ position.

Select the high-pressure setting and set the cooking time to 30 minutes. It will take several minutes for the Instant Pot to build up pressure before the 30-minute timer starts.

As soon as the cooking time is up, immediately release the pressure by flipping the valve to the ‘Venting’ position.

Preheat the broiler to medium-high heat. Remove the ribs from Instant Pot and place them on a rimmed baking sheet (line the baking sheet with foil for easy clean up).

Brush the ribs with barbecue sauce on both sides. See the Notes section below for finishing the ribs on the grill instead of under the broiler.

Broil for 3-5 minutes or until the sauce is bubbly and slightly caramelized.

Cut into individual ribs for serving.
