Unless you discount Kelly's Cornish Clotted Cream Ice Cream topped with Local clotted cream...just hear those arteries hardening....
If you haven't tried it you ought to have clotted cream and strawberry jam (Boddington's Cornish Strawberry jam) on saffron bread, preferably from Pearces Bakery in Kelly Bray, Callington. Their saffron bread has been winning gold medals for over a hundred years and they were chosen as one of Rick Stein's Food Heroes for their local produce of exceptional quality. Ultimate luxury as anyone who has been here will testify!
