How Pressure Cooker works and why it Reduces Cooking Time

Pressure Cooker

A pressure cooker is a sealed chamber that traps the steam produced by heating its contents. When steam builds up, pressure rises, pushing the boiling point of water above 212°F. In general, a higher temperature shortens cooking times and, due to less evaporation, removes flavor from foods more effectively.

How pressure cooker works

Water is heated and gradually boils into steam inside the tightly sealed pressure cooker. Since the steam cannot escape, it accumulates above the food. All of the trapped water molecules raise the pressure inside the cooker.

 And the pressure cooker traps the hot air and moisture along with the food, speeding up the cooking process. In other words, the moisture covering the food itself reaches higher temperatures than it does otherwise, speeding up the chemical processes involved in cooking.

Why Pressure Cooker Reduces Cooking Time

Since heat builds faster and retains temperature better under pressure, cooking time is reduced. The added pressure within the cooker raises the boiling point of water above 1000 degrees Celsius, allowing for more cooking time until the water begins to boil. As a result, food is cooked faster.
