Answer 1

Answer:

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. High pressure limits boiling, and permits cooking temperatures well above 100 °C (212 °F) to be reached.

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 high 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. After cooking, the steam pressure is lowered back to ambient atmospheric pressure, so that the vessel can be opened safely.

Almost any food that can be cooked in steam or water-based liquids can be cooked in a pressure cooker.[citation needed]

According to New York Times Magazine, 37% of U.S. households owned at least one pressure cooker in 1950. By 2011, that rate dropped to only 20%. 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.[1]

Answer 2

Kitchen gadgets only started proliferating in the 19th century and they were more important to the (mostly) men who invented and sold them, than the women who were expected to use them, and feel grateful for their help too. In fact, Wilson notes, gadgets simply increased kitchen work for most women, not least because they were sold as replacing the work of the servants who would have shared the burden earlier.

But the Instant Pot felt different. It was, writes Wilson, “a labor-saving device that factors in what a cook needs and feels.” This seems linked to its creation, which was not from a large corporation, but by an out-of-work software engineer, Robert Wang, who spent 18 months tinkering around with two other engineers to devise a product based on their real life experiences of cooking for their families — whether it was simmering stews, steaming rice, maintaining low warmth for yoghurt or boiling eggs. The Instant Pot did it all.
