Can you cook a steak in a pressure cooker article is about a vessel for cooking food in high pressure steam. Pressure cooking is the process of cooking food under high pressure steam, employing water or a water-based cooking liquid, in a sealed vessel known as a pressure cooker. Pressures up to one atmosphere above ambient are generally employed.
The pressure cooker was invented in the seventeenth century by the physicist Denis Papin, and works by expelling air from the vessel, and trapping the steam produced from the boiling liquid inside. This raises the internal pressures and permits higher cooking temperatures. This, together with high thermal heat transfer from the steam, cooks food far more quickly, often cooking in between half and a quarter the time for conventional boiling. Almost any food that can be cooked in steam or water-based liquids can be cooked in a pressure cooker. Part of the decline has been attributed to fear of explosion, although this is extremely rare with modern pressure cookers, along with competition from other fast cooking devices, such as the microwave oven. In 1679, French physicist Denis Papin, better known for his studies on steam, invented the steam digester in an attempt to reduce the cooking time of food.
His airtight cooker used steam pressure to raise the water’s boiling point, thus cooking food more quickly. In 1864, Georg Gutbrod of Stuttgart began manufacturing pressure cookers made of tinned cast iron. In 1918, Spain granted a patent for the pressure cooker to José Alix Martínez from Zaragoza. Martínez named it the olla exprés, literally “express cooking pot”, under patent number 71143 in the Boletín Oficial de la Propiedad Industrial. In 1935, the Automa pressure cooker was introduced.
Mountaineers attempting to climb Mount Everest took it along with them to cook in higher altitudes. In 1938, Alfred Vischer presented his invention, the Flex-Seal Speed Cooker, in New York City. Vischer’s pressure cooker was the first designed for home use, and its success led to competition among American and European manufacturers. Aluminium body, polyamide lacquered with an embossed aluminium lid and a stainless steel stirrup. On display at the Musée gallo-romain de Fourvière, Lyon. Also known as “old type” pressure cookers, these operate with a weight-modified or “jiggler” valve, which releases pressure during operation.
Some people consider them loud because the valve rattles as excess steam is released. Today, most pressure cookers are variations on the first-generation cookers, with the addition of new safety features such as a mechanism that prevents the cooker from being opened until it is entirely depressurized. These operate with a spring-loaded valve that is often hidden from view in a proprietary mechanism. This generation is characterized by two or more pressure settings. After the stove-top pressure cookers, in 1991 came the electric pressure cookers, called the “third generation” pressure cookers.
These include an electric heat source that is automatically regulated to maintain the operating pressure. An electric pressure cooker integrates a timer. There is no delayed cooking capability. Delayed cooking becomes possible and the controller shows a countdown timer when working pressure is reached. Third-generation electric, with smart programming, which includes pre-set cooking times and settings based on heating intensity, temperature, pressure and duration. This is the configuration used by the Ninja Foodi line of pressure cookers. The second configuration consists of a completely removable air fryer lid, with a protective pad for storage.
This is the configuration used by most other pressure cooker manufacturers, including Instant Pot. The approximate vapor pressure of water as a function of temperature, or when viewed sideways, the boiling point of water as a function of pressure. In a sealed pressure cooker, as the water boils, the steam is trapped in the cooker which raises the pressure. However, the boiling point of water increases with pressure resulting in superheated water. However, pressure cookers also use steam and water to rapidly transfer the heat to the food and all parts of the vessel.
