Regarding sell-by dates (apologies, @gfweb), I have three daughters, all of whom are kitchen-challenged. One doesn’t cook (her husband does); one specializes in hamburger helper, and the third lives with me and doesn’t even try.
I asked Child C, who with fam was coming to dinner, to stop and pick up a roll of foil. She said she had a roll and would bring it.
When she got here she handed it to me and said, “Mom, I think this foil may be expired.”
