Nestlé Kitkat Santa - 29g

KitKat sits at the very centre of the British sweet shop: lunchboxes, tea breaks, the vending machine at work. When December arrives, it turns up as Santa, alongside the selection boxes and the tin of chocolates that does the rounds after dinner.

People in Canada go looking for this one because the small things are what make it feel like home. Your parents put one in your stocking, so now one goes in your children's, and the tradition carries on a few thousand miles from where it started.

It is a little one, 29g, which is exactly why it works. It fits in a stocking, sits by a place setting next to the crackers, or slips into a card envelope with a bit of persuasion. Keep it in a cool cupboard, well away from the radiator and anyone with a sweet tooth.

Nestlé is behind plenty of the British chocolate people miss, from Quality Street to Smarties and Aero. A KitKat Santa tends to go in the basket with those, ready for a Christmas morning that looks the way you remember it.
