The Pressure cooker is a method of cooking in a sealed Pressure Cooker that does not permit air or liquids to escape below a desired pressure. Because water's boiling point increases as the pressure increases, the pressure built up inside the Pressure Cooker allows the liquid in the pot to rise to a temperature higher than (212 °F) before boiling.
