Kettle Foods has expanded the its Crispy Bakes range in the UK with the launch of a salt and malt vinegar offering.

The company has decided to extend the low-calorie range following consumer demand. Crispy Bakes are the low calorie alternative to the group's flagship brand Kettle Chips.

Kettle Foods brand manager Samantha Garnham said that almost four-fifths of Crispy Bakes sales come from "repeat purchase".

She added: This means that stocking Crispy Bakes will directly lead to an increase in overall sales, rather than cannibalising them."
