Editing Pressure cooker (section)

==== Cold water quick release ====

This method is the fastest way of releasing pressure with portable pressure cookers, but can be dangerous if performed incorrectly.  Hence it is safer to release pressure by using the other methods. The manufacturer's instruction book may advise against the cold water release or require it to be performed differently.

The cold water release method involves using slow running cold tap water, over the edge of the pressure cooker lid, being careful to avoid the steam vent or any other valves or outlets, and never immersing the pressure cooker under water, otherwise steam can be ejected from under the lid, which could cause [[scalding]] injury to the user; also the pressure cooker lid can be permanently damaged by an internal [[vacuum]] if water gets sucked into the pressure cooker, since the incoming water blocks the inrush of air.

The cold water release is most suitable for foods with short cooking times. It takes about 20 seconds for the cooker to cool down enough to lower the pressure so that it can be safely opened. This method is not suitable for electric pressure cookers, as they are not immersible. This type of pressure cooker cannot be opened with a cold water quick-release method.

The cold water release method is not recommended when cooking pulses e.g. red kidney beans, as the sudden release of pressure can cause the bean to burst its skin.
