What is a pressure cooker, and what does it do?
A pressure cooker works on a simple principle: Steam pressure. A sealed pot, with a lot of steam inside, builds up high pressure, which helps food cook faster.
When was the pressure cooker invented?
It was invented in the 1600s by a Frenchman by Denis Papin, who wanted to translate new discoveries in physics about pressure and steam into cooking. He called his pot the "Digester" but it took quite a while before better manufacturing standards and technology could make these high pressure pots safe.
How does a pressure cooker work?
A pressure cooker is a sealed pot with a valve that controls the steam pressure inside. As the pot heats up, the liquid inside forms steam, which raises the pressure in the pot.
