Bonkers
Nothing particularly bonkers about mince pies.
But there is something bonkers about festive produce that goes past its “best before” date half way through November.
Cadbury’s Creme Eggs used to be a seasonal item that only came out at Easter, but they gradually extended Creme Egg occasionality to cover the full twelve months. Maybe M&S is trying to do the same with mince pies. Can’t see it myself. It’s hard to think of any Christmas-specific stuff that might pull the Creme Egg trick, except maybe mulled wine spices, and they’re more of a cold/dark/wet thing than specifically for Christmas.
