Clotted cream is a thick cream made by heating full-cream cow's milk using steam or a water bath and then leaving it in shallow pans to cool slowly. During this time, the cream content rises to the surface and forms "clots" or "clouts", hence the name. It forms an essential part of a cream tea.
Although its origin is uncertain, the cream is associated with dairy farms in South West England and in particular the counties of Devon and Cornwall. The largest commercial producer in the United Kingdom is Rodda's at Scorrier, near Redruth, Cornwall, which can produce up to 25 tons of clotted cream a day.
In 1998, "Cornish clotted cream" was registered as a Protected Designation of Origin (PDO) under European Union law. The designation can be used if the production follows certain requirements, from milk produced in Cornwall and the cream has a minimum fat content of 55%. Following Brexit, the PDO was also registered under UK law. It is recognised as a geographical indication in Georgia, Iceland, Moldova, Montenegro, Norway, Serbia, Switzerland, and Ukraine.
