Cadbury Dairy Milk Golden Crips - 54g

Dairy Milk sits right at the centre of the British sweet shop. The purple wrapper is at every corner shop, petrol station and supermarket till, and the versions with something stirred in are where the real arguments about favourites start.

People in Canada go looking for this one because of a very particular memory: the bar bought on the walk home, the one eaten on the bus, the one hidden in the glovebox. Cadbury made in Britain is the taste that memory is set to, and nothing else quite scratches the itch.

It is a single bar, small enough for a coat pocket and big enough to feel like a proper sit-down. Keep it somewhere cool and dry, away from a sunny windowsill, and it will sit happily in the cupboard until you crack. Break it into squares with a cup of tea, or don't bother breaking it at all.

Most people do not stop at one. It tends to go into the basket with other bars from the purple shelf, a box of proper British tea and whatever else you have been missing since you left.
