You are in the wilds, and you just happen to be wanting a hot baked concoction! What do you do???
Simple! Build an oven, start a fire, wait, then enjoy (after cooling period).
After I look at the above equation I think that one of the steps might need some explaining, namely build an oven. Building an oven in the wilderness can seem intimidating, but with a little knowledge you might be surprised how easy it is!
Step 1: Gather Stone Oven Materials
You will need some stone for this oven. If possible get nice flat stones like flint, schist, or the like. Stay away from sandstone, round river rocks and most rocks found in/on water – those will have a tendency to explode when you heat them. The last thing you want when trying to improve your survival situation is the get yourself blown up – definitely not cool!
You should be looking for some stones that are flat and longer, these will act as a shelf or cooking rack to place your food on.
Once you have the materials, find some good level ground to start building.
Step 2: Build the Structure
When building the stone oven, you want to start with a flat area to build a fire on top of. You will be laying stones in a circle around the fire building area with an opening in the front (you will later be able to roll a stone over the opening to help keep air in.
You will want to start building the walls of the oven up. When you get about 6″ to 12″ in height, you will want to lay your long stone across the structure. This will act as a shelf for the food you are cooking to be placed upon. Once the shelf is laid, continue to build the oven up, and stagger the next row of stones toward the center about 4″ to 6″ (depending on the size of the stones you are using). The staggering of stones will slowly create a domed top to the oven. Be mindful of this point to leave a larger hole in the back toward the top of the structure to allow for the smoke to exhaust from the oven. The more aggressive the stagger of stacked stones the quicker you will be able to seal off the over, but the less stable the oven will be too.
Once you have placed a top stone on the oven you will want to find a stone that can be rolled over the remaining mouth or opening to seal in the heat. IF you can find a rock with a small hole in the bottom or a missing corner you will be gaining a great advantage to keep your fire properly oxygenated.
Step 3: Build the Fire and Cook
You are now ready to build a fire in the oven, and get form a strong bed of coals in the oven. Ideally, you will have enough coals to allow feeding of the fire periodically with a split log. Once this is accomplished you are ready to cook. Depending on how far your shelf is from the bed of coals, your oven will be between 300F and 500F temperature. Most items will be cooked satisfactorily at this temperature in 10-30 minutes. However, since each oven setup and fire is different results will vary.
If this is the first use of your oven, I would recommend checking in 5-10 minute intervals on the progress. While you wait, it would be advantageous to build some tools for future food retrieval from the hot oven. A slimly forked stick can serve many a purpose, and a particular eager person could even carve a full peel.
Regardless, be sure to have fun and stay safe!
