Best Before

Father Christmas kindly brings me one of these every year. This one has been in the cupboard for almost a year, although it's been open for a couple of months. It's not my favourite chocolate, so I only eat a slice when no other chocolate options are available. After a Metafit class this evening I was very much in need of a slice, and I noticed the best before date is next week - I think I'll just about manage to finish it in time!
