More than 100 professional and amateur bakers from Pennsylvania to Penzance are gearing up for this year's World Pasty Championships at the Eden Project.
Tomorrow's event will be the second time the event has been held at the eco-attraction, near St Austell.
Also known as the Olympics of the Oggy, the day-long competition in front of thousands of pasty fans celebrates Cornwall's most famous food export in advance of St Piran's Day on March 5.
Among the competitors will be Cornwall-born Mike Amery, who has flown from his home in New Hope, Pennsylvania, USA, to source his ingredients fresh from a farm before preparing what hopes will be the perfect pasty.
Mike 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.
"Sourcing fresh turnip for my pasty is part of it.
"We want to follow a turnip from farm to plate."
Mike plans to bake two different entries, a traditional Cornish pasty that adheres strictly to the European rules and in the non-Cornish category, one of his personal favourites, a lamb pasty with mint and a blending of traditional vegetables, all locally sourced.
Also competing will be Billy Deakin of Mount Hawke, Cornwall, last year's winner of the Cornish Pasty Amateur category.
This year he will be baking a Caribbean-style creation with oxtail, sweet potato and blended spices, as well as a traditional pasty.
