The Thin Core Forskolin  instructions for cooking with this plain-knob set are similar to the sets that operate with the steam value. When your food reaches the stage in the plain-valve set where you see or hear the steam being released from the steam valve, you will see and hear the lid bouncing slightly and steam will be escaping from around the lid.
