→Pressure Cooker for Energy Efficient Cooking
= Pressure Cooker for Energy Efficient Cooking =
A [https://en.wikipedia.org/wiki/Pressure_cooking pressure cooker] (retort) is very efficient, cooking food three-four times faster for a given energy input. A pressure cooker cooks food at a higher temperature, up to 120 C120°C. This reduces cooking time and saves energy.
Pressure cookers keep steam from escaping, thus increasing the air pressure inside. As air pressure is increased, the boiling point of water increases in temperature, too. This means that under pressure, food can be cooked at a higher temperature, i.e., faster, without boiling. For every 5 to 10 degrees Celsius that the water temperature increases in a pressure cooker, food will cook twice as fast.<ref>https://www.chefsteps.com/activities/pressure-cookers-the-faq</ref>
