I put the dozen in a pot filled with water and one floated up to the top, so I removed it. I boiled the rest and tried one to make sure I wasn't feeding my child something worse than usual. It was fine, even though the "best used by" date on the carton was April 11 and it's now the middle of June.
That wasn't the best use of day twenty-four, but it wasn't such a great day and somehow I managed to work in two 21s so I'm catching up. Some days you should just shuffle through. The ability to move on is a valuable skill.
