Nestlé Milkybar Giant Tube - 80g

In Britain, Milkybar is simply the white chocolate. It has been the sweet-shop name for it for generations: the one parents handed to small children, and the one those children quietly kept buying as grown-ups.

People in Canada go looking for it because the taste is tied to a very particular time and place. A school trip, a cinema bag, the back seat of the car. You cannot really explain it to someone who did not grow up with it, so it is easier just to open a tube and share.

The tube is the whole point. It fits in a bag, a glovebox or a coat pocket, and the buttons are small enough to hand out one at a time, in theory. Keep it somewhere cool and dry, away from the radiator and the sunny windowsill, and it sits happily in the cupboard until someone finds it.

It goes nicely alongside the rest of the British sweet shelf, especially a tube of Smarties, the other tube that never survived a car journey. Buy both and settle the old argument about which was better.
