We all use pressure cookers, or have seen them used at least, but who invented them and how did they rise in popularity?
Papin discovered quickly that the locked lid raised the boiling point of water and caused food to cook more rapidly. Specifically, meat cooked much faster, especially the tougher cuts of meat that were less expensive.
Ancient versions of the pressure cooker were extremely large and required their own furnaces to provide heat to them, so they were not common in homes. They were also dangerous, and explosions were common when people used them.
Eventually, Papin developed a safety valve that helped to release some of the pressure, making even the early versions much safer to use.
By 1919, pressure cookers had not changed very much. Spain gave a patent to Jose Alix Martinez in 1919, for his ‘express cooking pot’. They were still very large and were not very common in homes, but more people were interested in having one for themselves. Martinez wrote a pressure cooker recipe book in 1924 detailing 360 different recipes for use in a pressure cooker.
Pressure Cookers in the Home
The first pressure cooker for use in the home was invented by Alfred Fisher. He called his version the ‘flex-seal speed cooker’ and after he presented it, several big manufacturers set to work copying the prototype’s design and function. At the World’s Fair in 1939, several companies had their own perfected designs, but the most prominent was the version from National Presto Industries which had just rebranded itself to the ‘National Pressure Cooker Company’.
Today’s pressure cookers are far safer than their historical counterparts, including Indian and Korean pressure cookers. The locking mechanisms are secure, and there are other safety features such as pressure release valves. There is also no need for a dedicated furnace anymore. Stove top versions and electric versions are both popular, and each has their strengths.
The best electric pressure cookers are the height of technology when it comes to pressure cooking, including timers and other settings that come in handy. Many home cooks swear by adding pressure cookers and a few accessories to their cooking, whether they are cooking rice, beans, or a hearty stew.
Many materials are used to make them, but the most common models you will find are finished in stainless steel. A stainless steel pressure cooker maintains a constant temperature, which is the main reason that the material is widely used.
I hope this information has given you a little knowledge on how, and why pressure cookers are so popular in modern kitchens, and the journey that has taken place to create the modern appliances we all use today.
