I may get called out on this, but I love the DO liners you can pickup at Walmart or Cabelas, etc. I haven't used them with anything other than cobbler - but for those of you that DO when you are camping imagine making amazing cobbler and then pulling the liner out of the DO when you are done and your DO is perfectly clean! After I tried the first time I won't do it without them. Sure beats trying to boil water and scrape out all the left over crumbs and cobbler. Anyone else use these with breads or main dishes? Not sure how it affects the food by not being right on the seasoned oven. Cobbler doesn't matter in my opinion.
