Cornish Clotted Cream

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. Clotted cream is an essential ingredient for 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.
