Well, first you dig a hole. Then you have essentially an iron pot with a lid. You make batter/meat (meat not recommended) and put it in the pot to bake/cook like an oven. Then you light coals on fire (or setup a fire) and put the heat source both in the hole (gods, that sounds so wrong...I'm terrible at describing this) and on top of the Dutch oven. Wait, and use a tool to lift the lid to check on it. Bake, and eat.

...Gods, I did terribly at describing it.
