"Some people do find the idea of the crust on clotted cream worrying. They think it's gone off and even try to scrape it away," says Philip Rodda, whose family has been making clotted cream commercially near Redruth in Cornwall for more than 100 years. "But as far as I am concerned the crust is the best bit. It tastes richer and has a nice, almost nutty, texture."
He says the West Country tradition of clotted cream has much to do with the area's abundance of rich milk. Yet no one, it seems, is quite sure where the art of making what Gladstone called "the food of the gods" originated. One theory is that it came with the Phoenicians when they arrived to trade for tin around 500BC.
The longstanding friendly rivalry between Devon and Cornwall is reflected in clotted cream. Both counties claim it as their own and both maintain that theirs is the best. Custom has it that a true Cornishman will always spread on the jam first and top it with cream, while a Devonian will do the reverse.
