Place the meat in a large bowl or large container. Combine the marinade ingredients in a seperate bowl and pour it over the pork ribs. Marinate it for at least 4 hours. (Overnight marinating guarantees the best taste. The picture below is 24 hours marinated pork.)
Place the meat and vegetables into the pressure cooker. Set the time for 35 minutes. Wait until all is cooked and pressure is released.
