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.
Why is cooking quicker in a pressure cooker?
“And the pressure cooker traps that hot air and moisture with the food, which expedites the cooking process. “In other words, the moisture surrounding the food itself reaches higher temperatures than it would without the pressure, which speeds up the chemical processes involved in cooking.

Do chefs use pressure cookers?

How does a pressure cooker reduce cooking time?
As elevation increases, atmospheric pressure decreases, causing water to boil at lower temperatures, which lengthens cooking times. But a pressure cooker provides constant, precise atmospheric conditions inside the cooker, reducing cooking times even at high altitudes.
Why is it difficult to cook food on mountains?
The key factor is declining air pressure at higher altitudes. Falling air pressure lowers the boiling point of water by just under 1 degree Fahrenheit for each 500 feet of increased elevation. … Any food prepared with moist-heat methods, like boiling or simmering, will take longer to become fully cooked.
