PLAN No. 812. THE FIRELESS COOKER
Fireless cookers are now being made and used in hundreds of country homes. What is more pleasing to the farm woman than to put her dinner in the fireless cooker before she drives to town to market her products, and upon returning find it ready for serving?
The fireless cooker offers several advantages. The first economy of time, as the housekeeper may leave the food cooking without worrying about the results while she is engaged in other household duties or visiting her friends.
Some foods are improved by long cooking at relatively low temperature. The texture and flavor of tougher cuts of meat, old, tough fowl, and ham are improved by slow cooking. Cereals, dried legumes, and dried fruits are more palatable and wholesome when cooked for a long time. Soups and stews are delicious when cooked in the cooker. Baking, however, can not be done very conveniently nor satisfactorily in the ordinary homemade fireless cooker.

In some sections of the country economy of fuel must be an important consideration. The food for the cooker may be started on the wood or coal range when the morning meal is being prepared. In warm weather the use of the fireless cooker and a kerosene stove means not only economy of fuel, but also comfort.
The food to be cooked is first heated to boiling point on the stove in the cooking vessel and then this vessel, covered with a tight lid, is quickly placed in the cooker, where the cooking continues. The cooker is so constructed that the heat does not escape. For long cooking it is necessary to place in the cooker under the vessel a hot radiator. A soapstone is the best radiator and can be purchased at most hardware stores for 50 cents. A stove lid, a brick or disc made of concrete, heated and placed in the cooker, may serve as the radiator.
Directions: A tightly built box, an old trunk, a galvanized-iron ash can, a candy bucket, a tin lard can, and a butter firkin are among the containers that have been successfully used in the construction of fireless cookers.
The inside container or nest which holds the vessel of hot food may be a bucket of agate, galvanized iron, or tin. This nest must be deep enough to hold the radiator and the vessel of food but not large enough to leave much space, as the air space will cool the food. The inside container must have a tight-fitting cover, and straight sides are desirable.
The packing or insulation must be of some material which is a poor conductor of heat. The following materials may be used and they should be dry: Lint cotton, cotton-seed hulls, wool, shredded newspaper, Spanish moss, ground cork, hay, straw and excelsior.
Sheet asbestos 1⁄8 inch thick and heavy cardboard have proved to be the best lining for the outer container and the wrapping for the nest. Heavy wrapping paper or several sheets of newspaper may be used for the lining of the outer container, but the nest should be wrapped with asbestos or heavy cardboard to prevent the hot stone from scorching or burning the packing.

1. It is well to have the outside container large enough to permit four inches of packing below and around the sides of the nest. If a cooker is being made with two nests, six inches of packing should be allowed between the nests. Pack into the bottom of the lined outer container four inches of the packing. Place the nest or inside container wrapped with asbestos or heavy cardboard and hold steady while the packing is put around tightly and firmly until it reaches the top of the nest.
2. Make a collar, as shown in the [illustration], of cardboard, sheet asbestos, or wood to cover the exposed surface of the insulating material. This collar should fit tightly.
3. Make a cushion which when filled with packing will be at least four inches thick and will completely fill the space between the top of the nest and the lid of the outside container. It should fit against the top tightly enough to cause pressure when the lid is closed.
4. The outside of the fireless cooker can be made more attractive by staining or painting it. The lid may be held in place by screen-door hooks and eyes. The cooker may be placed on castors so that it can be easily moved.
