Pressure cooker test



A simple test to test if your pressure cooker is working properly:

Let a drop of water drop on the pressure cooker while sterilizing.
If the drop boils like underneath, the temperature is around 250°F(121°C) and the pressure cooker is working properly.

Why does this happen?
An operating pressure cooker is hot.
Quite hot to be honest.
It´s hotter than the boiling point of water at 1 atmosphere (212°F=100°C)
If the pressure cooker is of the "standard" kind, it will be 250°F=121°C hot.

Now, if you put a small amount of water(=a drop) on the surface of the lid of the pressure cooker (while the pressure cooker is under pressure), the drop of water will begin to boil vigorously and will evaporate in 2-3 seconds, since the surface of the pressure cooker is so much hotter than the boiling point of water at the atmospheric pressure.

If the pressure cooker doesn´t work propperly , if the pressure doesn´t build up as it should, the pressure cooker temperature will be the same as the boiling point of water at atmospheric pressure or only slightly above.
If you were to drop a drop of water on such a cooker, the drop would only sit there and slowly evaporate over the course of a longer time span.
