Mine isn't exactly old fashioned, but in my troop, we make _Insert name of fruit_ cobbler in a dutch oven. Start by pouring in as many cans of filling as you feel necessary. Then, on top of that, put enough plain cake mix in the pot. Then gently pour some mountain dew to substitute as sugar. Why mountain dew, because it is mostly sugar and water. Also, It mixes the the cake mix in with the filling. The "Dew" taste will cook off. To finish, mix thoroughly. To cook, place coals on sides and on top for conduction and convection. Then let this cook for an hour or so. Delicious to say the least.
