How do pressure cookers work and are they really much quicker?
by

1 Answer

Answer :

Pressure cookers work because when you increase pressure, water boils at a higher temperature. Water normally boils at 212 degrees F. Under 15psi of pressure (standard in a pressure cooker), it boils at 257 degrees F. Since your food is cooking at a higher temperature, it will cook faster.
