Clotted cream

Clotted cream is a treacle-thick yellow cream made by heating and then leaving unhomogenised cow's milk out in shallow pans overnight. Purists prefer the cows to come from the counties of Devon or Cornwall in England. Clotted cream is a required ingredient of a cream tea, which is indeed known outside the United Kingdom as a Devonshire Tea.

Those living outside the Commonwealth may manufacture a reasonable facsimile by combining whole milk with heavy cream two parts to one, heating at the very lowest possible heat for a couple of hours until a skin forms, leaving it undisturbed overnight, and then harvesting the skin and its underclots—one may do whatever one likes with the remaining milk.
