Nestle Milkybar Gold Block - 90g

Milkybar has been the white chocolate of British childhoods for as long as most of us can remember: the buttons in a lunchbox, the Kid in his hat and glasses on the telly. Gold is the grown-up branch of the family, sitting on the newsagent's shelf next to the bars everybody actually buys.

People search for it by name, and that is the giveaway. A craving this specific does not want something similar. It wants the gold wrapper and the taste that goes with it, the one you last had on a bus home from school or out of a petrol station on the motorway.

This one is a 90g block, broken into squares, which makes it easy to ration and easier not to. Keep it in a cool cupboard away from the radiator and it behaves itself. It lives happily in a desk drawer, and a few squares broken over ice cream will not be wasted.

Nestlé makes a good share of the British chocolate aisle, so it tends to go in the basket alongside an Aero, a Yorkie or a Kit Kat. Nobody needs to know how many.
