This was not actually my mistake, but last year we bought an expensive fresh turkey two days before Christmas, and unbeknownst to me, my husband decided to store it in the oven (mistake #1) then my son turned on the oven to cook something else, causing the turkey’s plastic bag to melt to the turkey (mistake #2).
We had ham for Christmas.
Once I learned that the thing had been unrefrigerated overnight, it was no longer going into my mouth. My husband was hoping I’d rethink that, so I was actually pleased when the melted plastic made it inedible even by his very lax standards.
