Pressure cooking principles are quite simple and the chances are good that you already know the basic physics behind how they work. A pressure cooker is a sealed pot, plain and simple. When the water inside a pressure cooker is boiled, steam builds and creates pressure. It is this higher pressure (typically 15 psi or pounds per square inch) which allows the food to cook quickly. Hereâs why: Water normally boils at 212ÂºF and no matter how much heat you add to it, it will never get any hotter.
