@jmzxy_120: The pressure cooker first appeared in 1679 as Papin's Digester, named for its inventor, 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. #Denispapin #pressurecooker#invension#History#edit#viral#fyp
