It is for many the very flavour of Cornwall.
For generations the Cornish pasty has kept hunger at bay and is a major export.
Now the iconic Westcountry snack is to be reinvented in crisp form in celebration of the miners' traditional lunch.
"Prop-a-tater" flavour will taste of potato and onion, a dash of black pepper and – controversially for the purists – carrot.
Cornish Crisp Company bosses have agreed to develop the new flavour to sell at the Cornish Mining World Heritage Site.
A penny from each bag sold will go to the Cornish Mining World Heritage Site.
All donations will go towards helping protect and preserve the Cornish and West Devon mining landscape.
Sue Wolstenholme, managing director for The Cornish Crisp Company said: "The name Prop-a-tater links in with the mining heritage, our wonderful Cornish potatoes and it sounds good too."
Members of the public will be able to decide between two versions of the recipe, one of which simply has more black pepper than the other.
On Saturday, samples of each version will be available for the public to taste at the Cornish Mining Stand at the Cornish Pasty Festival in Redruth.
David Rutherford, from the Cornish Mining World Heritage Site, said: "We are delighted to be working with the Cornish Crisp Company to produce a new flavour of crisps."
If all goes according to plan, the crisps will go on sale in November.
