Cookware Shop - Pressure Pot

By raising the boiling point by high pressure, they enhance the cooking efficiency greatly. Pressure pots have low aeration and lock the steam inside the pots. As steam increases, the inside pressure becomes higher and higher.

So you need to reduce the preessure before opening the lid after cooking; either by opening the valve and let the steam comes out to reduc e the pressure inside or set the pot aside for a period to let the inner pressure lowered down automatically. Thus pressure pots are fit for long-boiled soups.
