The functioning of a pressure cooker is very simple as indicated above. The cooker is a completely sealed pot that has valves which helps in controlling the steam pressure inside.

This pressure forces the liquid and moisture into the food helping them cook fast. The extra heat of pressure cooker also promotes browning and caramelizing of food.
