That was not a typo.
Visiting the in-laws this weekend, I found my MIL feeding the children raisins - I went to put the packet away and thought it was strange I didn't recognise the Sainsbury logo. Turns out they were best before June 1999. She has a reputation for being a bit cavalier with food (even by my standards - I find some of her methods fairly ) but I thought this was probably somewhat over the top.
When I suggested to her that it might be an idea to throw the bag away she told me she hates waste and would use them in a cake. The children seem none the worse for their close encounter with fossilised fruit, though.
