Questions this course answers

Why does a pressure cooker cook above 100 degrees Celsius at sea level?

Water's boiling point increases when pressure above its surface increases.

What is the purpose of the regulator valve?

The valve controls pressure by allowing steam to escape in a controlled way.

Why is natural or controlled release required before opening?

A rapid pressure drop can trigger explosive boiling of hot liquid.

Why does altitude affect open-pot cooking?

Water boils when vapor pressure matches surrounding pressure, which is lower at altitude.

Why should a household cooker not automatically be used for canning?

Food-preservation safety depends on tested processing conditions and suitable equipment.
