A pressure cooker is a sealed chamber that traps the steam generated as its contents are heated. As steam builds, pressure increases, driving the boiling point of water past 212°F. In general, this higher temperature shortens cooking times and, due to a lack of evaporation, extracts flavor more efficiently from foods.
Why is pressure cooker used for cooking?
At high altitudes atmospheric pressure is low. So at high altitudes liquids boil at low temperature when the food materials can not be cooked. To increase the boiling temperature of water by increasing the pressure above atmospheric pressure. Pressure cooker is used so that food materials can be cooked easily.
Why are pressure cookers better?
A pressure cooker cooks food about 30 percent faster than conventional methods like steaming, boiling, and braising. … Pressure cookers are especially useful for cooking at high altitudes. As elevation increases, atmospheric pressure decreases, causing water to boil at lower temperatures, which lengthens cooking times.
What is the science behind pressure cooking?
Inside the tightly sealed pressure cooker, the water is heated and eventually boils into steam. Since the steam cannot escape, it collects above the food. All those trapped water molecules increase the pressure inside the cooker.
