At this time of year, you will find rhubarb appearing in the shops. It will have been produced under forced conditions, (unless it is imported of course...) - English rhubarb is, of course, the best...
The unique vegetable - grown only by 12 producers in a 'rhubarb triangle' in West Yorkshire - has been granted Protected Designation of Origin status by the European Commission.
Producers now have the same geographical marketing protection afforded to more famous specialities such as Champagne, Parma ham, Cornish clotted cream and Roquefort cheese.
