On the Making of a Cardboard Box Oven Posted by Jim Macdonald at 07:30 PM *
Ideal for cooking Chili-Dog Casserole (see below) for Boy and/or Girl Scouts in camp:
Take a cardboard box, such as wine comes in. The top will become the oven’s door, for the whole thing will rest on what was once the box’s side, with the hinge to the left or right, as you will.
Line this box (including the inside of the door) completely with heavy-weight aluminum foil. You can use duct tape on the outside of the box to hold it in place. Make sure the cardboard on the inside is Completely Covered. (This is important.)
Punch two or three holes of perhaps a half-inch diameter on each side of the box, close by the bottom and close by the top as it will be used.
Construct a rack half—way up, using metal coat hangers. You can interlace the hangers with the top hanging-hooks toward one another, and it will be quite sturdy. If you’ve selected a properly sized box you can cut a couple of slits opposite one another in the two sides adjacent to the door, and thread the outside corners of the coat hangers into them, making it nice and sturdy. (The slits, of course, should be the minimum size necessary.
Take two metal pie plates. Place them bottom-to-bottom, in the bottom of your oven.
Put charcoal briquettes in the upper pan and light ‘em off. Each briquette gives you forty degrees (F) of heat in the oven, so for our chili-dog casserole you’ll need nine briquettes.
While the coals are heating up, make the casserole. Place it in the oven, close the door, and cook until done.
Serve it forth.
You can make biscuits, brownies, cakes, or whatever else you wish in this oven. The oven will last for several uses. (Do keep it away from flammables, as you would anything that gets hot, and don’t use it in an enclosed place, as you wouldn’t anything that produces carbon monoxide.)
