WAYS OF USING THE FIRELESS COOKER
1. Food cooked in liquid:
In all cookers where stone plates are not used, only such foods as are cooked in liquids can be prepared. Examples of foods cooked in this way are, meat soup, beef-tea, meat stews, vegetables, fruit, porridge, cereal, puddings, etc.
The prepared food is put into one of the food receptacles belonging to the cooker and is placed over a fire, until it has boiled for a few minutes. The cover is then tightly adjusted, and the dish quickly locked in the cooker, to conserve the heat that the food and liquid have absorbed.
2. Food cooked in dry heat by the use of stone plates:
In this method the food is cold when it is placed in the cooker, and all the heat is supplied by stone plates placed above and below the utensil containing the food. These plates are heated for about twenty minutes over a fire, before they are used in the cooker.
Examples of food cooked in this way are, roasts of meat; baked fruit, such as apples; baked vegetables, such as potatoes or beans; cakes, such as plain cake or fruit cake; quick bread, such as corn-bread and biscuits.
