Walkers Doritos are gearing up for winter nights in with sharing-based NPD.

A seventh flavour, Sizzling Fajita (rsp: £1.29), joined the range this week, while its ambient dip line-up has been extended with red pepper & pepperoni and nacho cheese (rsp: £1.30), taking the range to five-strong.

Walkers has also updated the design of the dips to look more similar to the chip range. It said retailers should benefit from a strengthened association between the chips and dips by merchandising them together.
