Best answer: Why does food cook faster in a pressure cooker than in an open pan?

Food is cooked more quickly in a pressure cooker because at the higher pressure (1 bar/15 psi), the boiling point of water rises from 100 °C (212 °F) to 121 °C (250 °F). The hotter steam is able to transmit its thermal energy to the food at around 4 times the rate of conventional boiling.
