Do not waste fuel; concentrate your cooking; when a hot oven is needed for roasting meat or baking bread, plan to cook at the same time other things which require a high temperature; potatoes can be cooked in the pan with the meat; other vegetables and fruits can be cooked in the oven; and if a coal fire is used, a variety of food can be cooked in a steamer on top of the range without extra fuel.
Have the ashes sifted and save the cinders, which yield a quick top heat.
Economize gas by using the minimum amount necessary to keep food cooking at the desired temperature. When the boiling point is reached a small supply of gas will maintain the temperature.
Fireless cookers save much fuel and unnecessary heat, and are especially useful for any food which requires long, slow cooking, or for those foods of strong odor which so often scent up the whole house.
