I have never ruined any food but one time while getting ready to get my dutch oven going I put some butter in it and set it by the fire to melt per the recipe. As I was doing that the park ranger came by and I was a little distracted. I went to remove the dutch oven to put the ingredients in and when I removed the lid the extra oxygen caused a flare up and burnt the hair on my face on one side. So on one side I had a couple inch long beard and on the other I was almost clean shaven. Luckily no burned skinned.
