Press BROWN/SEAR and START/ STOP on your Crockpot™ Express Pressure Cooker and allow to preheat.
Add 1 tablespoons oil, preheat. Brown ribs, you will need to do this in batches so add a little more oil if required. Mix the remaining ingredients in a large bowl and coat ribs.
Place steaming rack and ½ cup beef stock in the inner pot. Return ribs on rack, pouring over any excess marinade. Secure the lid ensuring the steam release valve is in the seal (closed) position and press MEAT/STEW. Set the time for 15 minutes (depending on the size of the ribs) and press START/STOP. Once finished cooking, allow a natural pressure release time of 2 minutes.
Carefully remove the ribs and place into a warmed serving bowl. Press BROWN/SEAR then START/STOP and allow the sauce to bubble and reduce slightly, this will thicken the sauce. Garnish with the fresh parsley leaves.
