Pressure cooker, hermetically sealed pot which produces steam heat to cook food quickly. The pressure cooker first appeared in 1679 as Papin’s Digester, named for its inventor, the French-born physicist Denis Papin.
The cooker heats water to produce very hot steam which forces the temperature inside the pot as high as 266° F (130° C), significantly higher than the maximum heat possible in an ordinary saucepan.
The higher temperature of a pressure cooker penetrates food quickly,
reducing cooking time without diminishing vitamin and mineral content.
However, the new invention faced some challenges; it was difficult to regulate the pressure generated inside
the vessel and many pressure cookers at that time exploded.
Another issue faced with the design was the difficulty in producing the vessels made from a single sheet of metal (the machine stamped pots).
John Evelyn, a highly recognized Horticulturist, was present at the event. In his diary,
John Evelyn noted that the supper prepared by Denis Papin revealed how the pressure cooker could be used to cook and soften the hardest bones found in beef and mutton.
In his words, “the hardest bones of beef itself, and mutton were made as soft as cheese without water or other liquor, and less than eight ounces of coal.” From his descriptions, it was obvious that John Evelyn and many other guests were impressed with the outcome after using a pressure cooker.
The first version of the pressure cooker was unveiled publicly in 1679 it was called the Steam Digester.
Denis Papin discovered a way to design a vessel made from cast iron that had the features of a pot.
At such a high-temperature tough foods and bones cooked in the vessel became remarkably softer after cooking for a short time.
One of the industries that have been influenced by the use of pressure cookers
is the canning industry.
The process of canning foods was introduced as a means to preserve foods for longer periods.
Canned foods could last longer
and were suitable to match the lifestyle of many consumers.
They could buy canned foods
and keep them until the foods are
consumed. Canned foods made
it possible for people to buy meats
and fish without fear of the foods spoiling.
