How to you build a oven in the bush very primitave?
A simple oven can be made of many things, bricks made of mud held together with more mud, but it will fall apart rather quickly. A simpler way is one the boy scouts use. A cardboard box lined with foil, a couple of wire coathangers to make a shelf (rack) in the box (box will be used on its side), make a door out of the lid (inside lined with more foil). Take a pie pan, place hot coals from your fire in the pan and place it in the bottom of your oven. Place item to be baked in a pan on the shelf close the door and give it some time. Biscuits may take 20 to 30 minutes in the “Oven” to bake. Any metal box placed over hot coals can bake items. In the artic I saw someone bake biscuits in an old tool box using foil to make a pan.
