M&S Colin the Caterpillar Cola - 170g

Colin the Caterpillar is a fixture of British life. He is best known as the chocolate caterpillar cake that turns up on office desks and birthday tables right across the country, and these sweets carry his name from the cake aisle into the sweet aisle.

Here in Canada, people go looking for him because there is no M&S food hall round the corner. Some had a Colin cake every birthday growing up. Others just remember grabbing a bag at the station before a long train journey and having it gone by the second stop.

The 170g bag is a sharing size, which is a hopeful way of putting it. Keep it sealed in a cool, dry cupboard, clip it shut once it is open, and it is ready for film night, a road trip or a lunchbox that needs cheering up.

People rarely buy one M&S thing on its own. Colin usually ends up in the basket next to a few other bits from the M&S shelf, the things you used to pick up without thinking and now cannot stop thinking about.
