Here is my apple box oven.
It took about two hours to put it together. I'm sure it would be a bit faster if I made a second one but I was learning...
My plan is to grind some corn meal and make some corn bread to go with our soup for supper.
I have my pans that fit (cookie sheet, Texas sheet cake pan and round cake pan) but I wasn't able to find a cookie cooling rack in our little town. The next time we go shopping I will see if I can find one at Walmart. But I can put supports in and set my pan on the supports for now.
I do have the thermometer but haven't pushed it through yet. I will have my DH help with that. He has an awl.
This is the rack that I will use for now - until I can get to a bigger town.
It will work just fine as the purpose is to hold the pans above the coals.
Of course I will do this outside on a safe non burnable surface. :-)
