In a small bowl, mix the spice rub ingredients
Rinse ribs and pat dry with paper towels. Remove the membrane on the back of the ribs.
Season the baby back ribs generously on both sides with the spice rub.
Place the trivet (or rack) in the bottom of your pressure cooker. Add enough water and the apple cider vinegar.
Place the ribs inside the pressure cooker, standing up and wrapping around the pot. Close the lid and set the timer around 30 minutes
Once done, allow the pressure cooker to natural release.
While the ribs are cooking, prepare the BBQ sauce. Place all the ingredients (except the ribs cooking liquid) in a small saucepan and stir to combine. Simmer on low heat for about 15 to 20 minutes, stirring occasionally.
Remove the ribs from the pressure cooker and place them on an aluminum foil lined baking sheet. Brush them generously with the BBQ sauce (on both sides), and place them under the broiler for about 5 minutes or until slightly charred. Serve with the remaining BBQ sauce.
