Pies in dutch ovens:
Three beer bottle caps in the bottom of the dutch oven hold the pie pan up off the superheated bottom, and alow for air flow like a convestion oven. A home made wire rack alows for a second pie pan to be perched above the bottom one.
I have a matched pair of 16 qt ovens (with legs, otherwise they are not an oven). I have never cooked meat or other protien or fat in them. They are seasoned with canolla oil... 6 oil baths when they were new. These two ovens are ONLY USED FOR BISCUITS, BREADS, AND PIES, and my familly knows that they are not to even look at them, moreless touch them.
The ability to create 24 biscuits, 2 12" cornbreads, and 2 pumpkin and 2 keylime pies means that I have never yet gone camping with anyone who doesn't regularly re-invite me.

Bob, All that stacking and turning...what are you trying to do? Give away all our secrets? BTW, the formula for temp given by BigBob is the same basic one that I use, but it needs to be adjusted thusly: add one cosal to the bottom and two coals to the top for every drop of 10 degrees below 40...ie one step up at 30, two steps up at 20, three steps up at 10 etc. Also add coals (dont know formula) when you go up in altitude. I learned the hard way that coals burn cooler due to less oxygen the higher you go. You can barely bake at 9500 ft.
PS, Bob, I love the quote in your sig.
I have been using it often in everyday life since I first saw it.
