I am a little over the constant criticism of McDonald's as if it is the devil's own fast-food chain. On those rare occasions when one utters the phrase "Appellation d'Origine Controlee" - say, when mangling it in an attempt to appear sophisticated at a party - it may be with thoughts of Champagne from that region of France, or Parma ham from the pampered pigs of Italy.
We may not realise it, but that exalted designation also applies to the humble Cornish pasty. Anyone can make a pasty, but European Union laws decree that a Cornish pasty can only be called such if: it is made in Cornwall; is a distinctive "D" shape; is crimped at the side (never on the top); and is filled with contents that can reasonably be described as "chunky".
Cornish pasty-makers are not only struggling to preserve their product's special designation, they are also fighting a rearguard action against a 20 per cent value-added tax that was slapped on the retro snack in this year's British Budget.
Sausage and bacon rolls, rotisserie chickens and a host of other hot, filling goodies have felt the weight of the levy, but only the pasty has its very own pressure group - the Cornish Pasty Association.
