Nestle Yorkie Raisin and Biscuit - 66g

Yorkie has always been the hefty one on the newsagent's shelf, the bar with blocks thick enough to make your jaw earn it. The raisin and biscuit version has its own loyal crowd, the people who walk straight past the plain one without a second glance.

When someone in Canada goes looking for it, they are usually chasing one particular moment: a lunchbox on a school trip, a flask of tea on a freezing touchline, a bar split badly in half in the back of the car. It has to be this one, because this is the one in the memory.

It is a single bar, and a 66g Yorkie feels heavier in the hand than the number suggests. Keep it somewhere cool and dry, well away from the radiator, and it will sit quietly in the cupboard until somebody finds it. It slips into a coat pocket, a desk drawer or a parcel for someone back home in spirit.

If you are putting together a box of British chocolate, it sits well alongside other Nestlé favourites like a KitKat or an Aero. Add a mug of strong builder's tea and the afternoon is sorted.
