What is a "pressure cooker"?

A pressure cooker is a kitchen appliance used for cooking food quickly under high pressure and temperature. It typically consists of a tightly sealed pot with a locking lid and a pressure release valve. When heated, the liquid inside the pot produces steam, increasing the pressure and raising the boiling point of water, which significantly reduces cooking time. Pressure cookers are versatile tools suitable for cooking a variety of foods, including meats, beans, grains, and vegetables, while retaining nutrients and flavors. They are valued for their efficiency, convenience, and ability to tenderize tough cuts of meat in a fraction of the time required by traditional cooking methods.
