Nestlé Aero Peppermint Sharing Bar - 295g

Mint Aero sits in the same corner of a British sweet aisle as the after-dinner mint and the bar bought for a long car journey: a bit cooling, a bit grown-up, gone far too fast. In the UK the green wrapper is about as familiar as a bus stop.

People in Canada search for it by name because the taste is the thing they remember, and memory is very fussy about chocolate. If the bar at your nan's was the British one, that is the one you are after.

A sharing bar is a slab you break into squares, and the bubbly ones give that satisfying dull snap. It keeps happily in a cool cupboard, away from the radiator and from anyone who claims they are just having one. Some people swear by it straight from the fridge, and they will tell you so at length.

Nestlé's British line-up runs well beyond Aero, from KitKat to Rolo, and plenty of people end up with a small pile at the till. A few squares of mint Aero next to a pot of proper tea is a perfectly respectable evening's plan.
