As the pot is heated, the temperature inside increases until the water starts to boil. … At that pressure, water boils at 121°C (250°F). That means food can cook at a much higher temperature than it ever could at atmospheric pressure—and since cooking reactions speed up at higher temperatures, your food cooks faster.
How do pressure cookers cook faster?
“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.
Why food is cooked quickly in a pressure cooker?
Pressure cooking requires much less water than conventional boiling, so food can be ready sooner. Less energy is required than that of boiling, steaming, or oven cooking. Since less water or liquid has to be heated, the food reaches its cooking temperature faster.
