 the fireless cooker extensively, especially for cooking certain meats, cereals, 

 and other foods requiring a long application of heat. For example, 

 the diminished shrinkage in hams when cooked in a fireless cooker has led

If a coal fire must be built in order to accomplish the initial heating 

 of the food, the utilization of the heat as the fire is dying down must be
