Which British corner shop staple do you rank as the true national treasure?

An institution stronger than most political parties. The lunchtime maths of 'is this actually £3.50 worth it?' unites the entire nation.

Once 10p, now practically requiring a mortgage advisor. The Freddo price is the unofficial inflation index of Britain.

A slightly warm pastry parcel that has saved more motorway journeys than the AA. Cornwall may weep, but the nation eats.

The colour-coded flavour debate has ended friendships. Salt and vinegar in blue or green? Choose wisely.

Marketed as sports fuel, actually consumed exclusively at 10am on a Sunday after questionable decisions. Absolutely irreplaceable.
