Fire Baked Cornbread

Today I went in our field after it was picked and gathered excess corn.I had a pocketful of corn and I didn't know what to do with it.Then I took a stone and a piece of wood and started to grind it.Then my dad said to go get the almost square rock and he would grind a bowl into it and he did. So then I started to grind the corn into meal.Then we mixed it with flour,water,oil,and baking soda. After that we baked it on the fire and it turned out pretty good.You could try this at home if you have a square shaped rock,a grinder,some field corn,a fire,time,effort,and someone willing to do it.
