Mars 3 Pack - 118.2g

The Mars bar is the chocolate bar Britain measures the others against. It has sat on every newsagent's counter for as long as anyone can remember, and it turns up in packed lunches, glove boxes and the bottom of football bags.

People in Canada go looking for it because the taste is tied to a place. One bite and you are back outside the chippy, or on a wet bench at half time. The UK bar is the one they remember, and that needs no explaining.

The pack holds three bars, 118.2g in all, which works out as one for now, one for later and one for whoever finds them first. Keep them somewhere cool and dry in the cupboard. Some swear by the fridge for extra snap. Some deep fry them, and we leave that between you and your conscience.

Mars is also behind Galaxy, Maltesers, Twix and Bounty, so the bar rarely travels alone. A Mars, a Twix and a strong cup of tea is a balanced afternoon by most British standards.
