K, P the pressure and V the volume of the gas considered. So if you increase the pressure inside the pan, the air and the water vapor increase in temperature, which cooks the food faster.

Why pressure cooking is faster?

What temperature in a pressure cooker?

Principle. The boiling point of water depends on the atmospheric pressure, the increase in pressure allows the cooking temperature to rise above 100°C (up to 118°C). A valve releases the steam as soon as the absolute pressure exceeds 1.8 bar.

Why the pressure cooker?

Its main argument is that it saves time. It cooks twice as fast as a traditional Dutch oven. As a result, it also saves energy! Thanks to its contained and rapid cooking, it preserves the vitamins, in particular vitamin C (one of the most fragile), the nutrients and the minerals.
