Sensations Balsamic Vinegar & Caramelised Onion- 150g

In Britain, Sensations is the Walkers bag you buy when people are coming round. It sits a step up from the lunchbox packet, and balsamic and onion is the flavour people tend to name when they say they like the posh ones.

Here, the trouble is explaining it. You can tell a Canadian friend it tastes of balsamic and caramelised onion, and they nod politely, but you know that is not the half of it. So you search for the actual bag, the one with the name you remember, because nothing else scratches that particular itch.

This is a 150g sharing bag, the size meant for a bowl rather than one person on the sofa (though nobody is checking). It keeps happily in the cupboard until the evening it is needed. Once it is open, a clip helps, if there is anything left to clip.

People rarely buy just the one. It goes in the basket with the rest of the Walkers shelf, a lump of strong cheddar and a jar of pickle, and suddenly a quiet Friday night has turned into a proper spread.
