Ready salted crisps are no longer the nation’s favourite flavour, as cheese & onion has now taken the top spot. The market for cheese & onion crisps is worth £256m, according to Mintel research, with sales having increased an impressive 15% in the last two years. Valued at £244m in 2006, ready salted crisps have slipped into second place, despite an increase in sales of 5% over the same two-year period.
