[1] In around 1878 a Jersey farmer, Hugh de la Haye, showed friends a large potato that he had bought.

They cut this potato into pieces, which they planted in a côtil (a steeply sloping field) above the Bellozanne valley.

One plant produced kidney-shaped potatoes, with a paper-thin skin, which they called the Jersey Royal Fluke.

[3] Ninety-nine percent of production is exported to the United Kingdom.

[4] Under the Common Agricultural Policy of the European Union Jersey Royals are covered by a Protected Designation of Origin (PDO).
