Smiths Frazzles - 41g

Frazzles live at the lunchbox, after-school, pub-snack end of British snacking, next to a glass of squash or a pint depending on how old you are now. They have been in that spot for as long as most people can remember, which is exactly the point.

People in Canada search for them because the taste is tied to a time and a place: a cold walk home, a bag split down the side and shared round, a packed lunch that was mostly about the crisps. You cannot describe that taste to someone who has never had it. You need the bag.

This is the single 41g bag, the one you would grab from a corner shop on the way somewhere. It keeps happily in the cupboard until the craving strikes, which tends to be around half past three. Fold the top over if you have any willpower left. Nobody does.

Smiths make a wider range of British crisps and snacks, and Frazzles rarely travel alone. Most people add a few more bags from home to the order, plus a bar of chocolate for afterwards, because a crisp needs a pudding.
