When you need to build a hot cooking fire in minimal space, which can be put out in a matter of seconds and will require minimal fuel to cook your dinner, you need to look no further than the Dakota Fire Hole. Take a look at this efficient design below.

Named after the Dakota Indians who used this design to construct fires which could not be seen by the enemy and which could be put out in a matter of seconds when they needed to dash away, this method is highly efficient at producing a powerful flame without using a great deal of fuel.

Due to the secondary hole, you can feed the fire safely without having to worry about being burned, which is excellent when you have something that takes more than a few minutes to cook. Try digging one of these out on your own. Practice makes perfect, though, so it's best to try it on your neighbor's lawn first.
