Automatic high energy saving cooker

A dual-voltage, energy saving, electric pressure cooker is designed with a thermally insulated cooking pot, spaced-apart support on the bottom of the pot to prevent food from sticking to the bottom, a unique, hinged, sauce-pan style handle for sealing and unsealing the pot using one hand, a built-in modem that supports the remote operation of manual or preprogrammed cooking controls by telephone or computer. The energy saving is accomplished in a two-mode pressure cooking process. Cooking mode one is active heating or steaming for a short, but controlled period of time, as the liquid inside the pot reaches a temperature of approximately 120° C. (250° F.). Heating is then discontinued and foodstuffs are subsequently cooked to perfection in a second cooking mode wherein latent heat from the first cooking mode completes the cooking process without additional heat being added.
