Monster Munch Roast Beef - 40g

Monster Munch sits in the crisp aisle but plays by its own rules. It is not quite a crisp. It is a chunky, crunchy claw that rattles in the bag and has started more playground arguments about who got the big ones than anything else in the lunchbox.

From Canada, people search for it because the flavour is impossible to explain to anyone who did not grow up with it. Roast beef, on a snack shaped like a monster's foot? You either know, or you are about to.

This is the single 40g bag: one person, one sitting, no sharing required. Kept sealed in a cool, dry cupboard it waits patiently. Once opened, it lasts about four minutes. It goes in a packed lunch, a coat pocket or, for the brave, straight into a buttered sandwich, where it is crunched flat in the proper British way.

Walkers is the name behind a good share of the crisps Britain grew up on, and Monster Munch tends to end up in the basket next to a few other bags from home and something fizzy to wash it all down.
