How can I make a haybox cooker that reduces smoke
From Audiopedia - Accessible Learning for All
To save even more fuel, use a haybox cooker to keep food warm or to simmer it after it has come to a boil on your stove. This cooker can cut fuel use by more than half when cooking beans, meat, rice, or grains. Rice and grains will use ⅓ less water, because not as much water will evaporate.
Make a haybox by lining a cardboard box with 4 inches of hay (or use straw, sawdust, old clothing, feathers, chaff, cotton, wool, styrofoam, or corrugated cardboard). Leave space inside the box for your cooking pot and for more insulation on top of the pot. The lid of the box should fit tightly.
When using the haybox cooker, remember:
Keep the hay cooker away from an open flame.
