Competitors from across the world are taking part in the World Pasty Championships.
More than 100 professional and amateur bakers are at the Eden Project in Cornwall in the second annual celebration of the dish.
The pasty was favoured by West Country miners who used the crimp as a handle to eat it while working underground.
In 2011 the term “Cornish pasty” was given protected status by European lawmakers.
‘Judgment day’
It means only pasties made in Cornwall can claim to be Cornish pasties, typified by being crimped on the side.
But some people dispute whether the dish of meat, potato, onion and turnip in a pastry casing originates from Cornwall or neighbouring Devon.
Among the competitors is Cornwall-born Mike Amery, who flew from his home in Pennsylvania to source his ingredients fresh from a farm before preparing what he hopes will be the perfect pasty.
Mr Amery said: “Anyone in Cornwall knows that the pasty and the folklore around it ignite so much passion.
“Pasty-making is like a religion and the World Pasty Championships is, in a sense, judgment day.”
