This specialty of Devonshire, England (which is why it's also known as Devonshire or Devon cream) is made by gently heating rich, raw milk until a semisolid layer of cream forms on the surface. After cooling, the thickened cream is removed. Clotted cream can be spread on bread or spooned atop fresh fruit or desserts. The traditional English "cream tea" consists of clotted cream and jam served with scones and tea. Clotted cream can be refrigerated, tightly covered, for up to 4 days.
