Consider the following statements

1. Food cooks faster at higher atlitude in pressure cooker, as due to lower pressure, boiling point is reached faster.

2. Food cooks faster at higher altitude in pressure cooker, as due to lower temperature, the boiling point of food is lowered.

Explanation:

At high altitudes, the pressure cooker is an essential kitchen tool. By cooking under pressure you are in effect increasing the atmospheric pressure and therefore, increasing the boiling temperature of water. Food will cook faster and more thoroughly.

Pressure cookers come with one or more pre-set weighted gauges. If your pressure cooker only comes with one weighted gauge, you will need to increase the cooking time to account for the lower cooking temperature at higher altitudes. If the pressure cooker has more than one weight, you may be able to make the needed adjustment by using the higher weight. Be sure to follow the directions that come with the pressure cooker for making altitude adjustments for the type of pressure cooker you are using. If there are no recommendations for altitude adjustment, contact the manufacturer directly.

To prevent water evaporation, once the desired pressure is reached on the pressure cooker, the heat can be reduced. Regulate the heat under the pressure cooker to maintain a steady pressure at, or slightly above, the correct gauge pressure. Check the manufacturer's directions for maintaining pressure.
