What is a haybox? It’s basically an insulated box in which you place your partly
cooked food. The heat energy held in the pot and the food completes the cooking process
without any external heat input.
Haybox cookers are so called because the early versions used hay as insulation. It
is also referred to as fireless cooking or retained heat cooking.
Various forms of haybox cookers are used widely in the developing world to cut down
on the use of firewood. This saves time spent in gathering fuel and helps reduce
deforestation. Conservative estimates of fuel saving vary from 30 – 50 %.
