The most common kitchen appliance used today, the pressure cooker was invented by French scientist, Denis Papin in 1679.
He introduced a device named ‘digester’ and presented it before the Royal society in London. The steam digester cooked food under high pressure at temperatures much higher than those achieved in a pan. The steam built up increased the boiling point of water and cooked food in less time. The dinner served at the Royal society impressed quite a few!
The pressure cooker was a precursor to ‘autoclave’, a device used to sterilise medical equipment. Pressure cooker saves a lot of fuel. Thus making it highly energy efficient.
