A brand of clotted cream called 'Definitely Devon' was criticised yesterday after it emerged it is actually made – in neighbouring Cornwall.
Robert Wiseman dairies, which make the product, has been labelled "naive" and "short-sighted" after re-igniting a long-running feud between the two counties.
The cross-border rivals have long been at war as to where the cream tea – the main ingredient of which is clotted cream – orginated.
Yesterday, Devon farmers were furious after it emerged the clotted cream was actually made in Scorrier, near Redruth – over 60 miles from the county border.
And to add insult to injury, the packaging instructs buyers to make a cream tea using the Cornish method, of adding jam first and then cream on top.
Bosses at Langage Farm, near Plymouth, said Robert Wiseman clearly had "no idea" about the importance of Devon's history of clotted cream, branding it a travesty the Cornish-made product was "latching onto our heritage".
Manager Paul Winterton said: "Our Devonshire clotted cream is made in Devon and it is something we are fiercely proud of. I don't understand for the life of me the decision by Wiseman to call it 'Definitely Devon' if it is made or processed in Cornwall."
"To be honest if they needed somewhere else to process their cream they could have come to us. I would gladly discuss with them using our facilities to rectify this situation."
Robert Wiseman took the decision to move the production of Definitely Devon from their Okehampton factory to Scorrier at the beginning of the month. The company use Devon milk for the product, which is then transferred to Cornwall, where it is turned into clotted cream before being distributed to private farm shops and supermarkets across the South West.
Mike Pearce of Cornishcream.com said: "The whole thing is a bit strange. You would imagine if they wanted to proudly call it 'Definitely Devon' they would at least make it there."
A spokesman for Robert Wiseman dairies said: "On the fourth of April we moved production of our Definitely Devon clotted cream to a factory in Cornwall.
"We contacted Trading Standards on the matter and were advised to include a 'Made in Scorrier' sticker on our product which we have done."
