Cook on high pressure for 20 minutes, and allow pressure to release for 10 minutes. After 10 minutes, release all remaining pressure.
Place a cup of water in the water pan of your smoker.
Add wood chips and allow the ribs to smoke for 30 mins to an hour until they are browned, and acquire a smoky flavor.
Place the cooked ribs on the smoker rack.
Allow to sit in the smoker for one hour at 250.
Remove, and Serve. Brush with additional Barbecue Sauce if desired.
Tips:
Apply the dry rub the night before/morning before to allow that Mexican spice to penetrate the baby back pork ribs.
Pressure cook and smoke the ribs before adding any sauce so you can taste the smokey meat. Add sauce on the side.
If you like your ribs more tender, pressure cook them longer. I like my ribs tender, but not "falling off the bone," so I haven't tested this recipe cooking longer than written.
