I used to work in a factory where we packed, among other things, clotted cream and the Tesco Finest clotted cream and Somerfield own brand are identical. In fact, there were about four brands of cream we packed that were all the same; Tesco Finest, Somerfield, Asda and something else. Have a look at the packaging on them and you'll see that they're all the same size and shape plastic punnets of cream with the same cardboard sleeve around them, just with different things printed on it.
