M&S Colin the Caterpillar Cherry - 170g

M&S sweets have their own corner of British snacking, and Colin is the face of it. He made his name as the chocolate caterpillar cake that appears at birthdays, leaving dos and any office with a reason to celebrate, and he has been wriggling onto other things ever since.

People in Canada go looking for Colin because the name does a lot of work. It is the party table, the school friend's birthday, the bag passed round in the back of the car. There is no M&S food hall round the corner here, so the search starts online.

The 170g bag is a decent size for sharing, or for pretending you are going to share. Fold the top over and it keeps happily in the cupboard. It goes in lunchboxes, desk drawers and film nights, and it is a cheap way to make someone who grew up in Britain smile.

Colin rarely travels alone. People tend to pick him up alongside other M&S bits and a few more British sweets, building the kind of haul you used to bring home from the shop on a Saturday.
