Conserve Fuel Consider the amount of cooking time needed for particular foods. If you have limited heat for cooking, choose foods which cook quickly. Many foods can be skewered, grilled or wrapped in foil and cooked in the fireplace. If gas is cut off, but you still have electricity, use electric skillets, hot plates or coffee makers to heat food. Devices using candle warmers such as fondue pots may be used if no other heat sources are available.
Camp stoves and charcoal burners.
These may be used outside your home. Never use fuel-burning camp stoves or charcoal burners inside your home, even in a fireplace. Fumes from these stoves can be deadly. Do not cook frozen foods unless you have ample heat for cooking. Some frozen foods require considerably more cooking time and heat than canned goods.
