The straight cast iron ones are best for camping (particularly the ones with feet that keep it up off the charcoal). You can make a simple fruit cobbler when camping. Make sure to season the dutch oven first (google it - you can do it in your oven or in a BBQ; it gets smoky).
Once you've seasoned your DO:
Dump one 1 yellow cake mix into the bottom of the DO.
Pour on 1 large can fruit pie filling (peach, cherry, apple, etc.) or even canned/bottled fruit and the juice.
Pour a can of Sprite over the whole thing. Do not mix.
You can google the right # of briquettes to use (i.e. for a 12" oven, use 10 briquettes on the bottom and 14 on the top).
Makes a nice little cobbler - add whipped cream and enjoy!
