Cadbury Double Decker - 4 Pack

The Double Decker belongs to that sturdy tier of British chocolate bars you could buy with pocket money: the newsagent's counter, the school lunchbox, the vending machine at the swimming baths. Never fancy, never trying to be. Just reliably there when you needed it.

When someone in Canada goes looking for one, it is usually because a craving has turned up without warning. A friend back home posts a photo, or you remember a rainy bus shelter and a bar in your coat pocket. Once the idea is in your head, nothing else will quite do the job.

This is a multipack of four bars. Keep it somewhere cool and dry, away from the radiator and the top of the fridge, and it will sit quietly in the cupboard until someone notices it. Then it goes into lunchboxes, the work drawer everybody knows about, and the glovebox on a long winter drive.

People tend to pick it up alongside other Cadbury favourites, a Dairy Milk or a Wispa, plus a box of proper tea to dunk nothing into and drink with it anyway.
