Historian and food writer Peter Brears has claimed that the Cornish pasty was in fact invented in London.
Writing in food studies journal Petits Propos Culinaires, he said pasties in Cornwall in the 19th century were mostly vegetarian, and the term "Cornish Pasty" was coined by cooks working around that time in London.
He said the elements that make a Cornish pasty unique have no relation to Cornwall.
He also said the special privileges and protection granted to Cornish pasties - and the restrictions on bakers making Cornish pasties across the rest of the UK were "totally bemusing".
The Cornish Pasty Association said the EU protection won made no claims on where the origin of the pasty came from.
