While there are many good fireless cookers on the market which cost from
five to twenty-two dollars, according to size and make, it is possible
to construct a home-made cooker which will give very satisfactory
results and will be considerably cheaper than one which is purchased in
the shops.
Materials required: A box or some other outside container; some good
insulating or packing material; an inside container for the kettle, or a
lining for the nest in which the kettle is placed; a kettle for holding
the food; and a cushion, or pad, of insulating material, to cover the
top of the kettle.
