Well wanna-be clotted cream, I guess. But from what I've heard it tastes much better than normal clotted cream.
I found the recipe online and made it to go with the cranberry orange scones. It's really simple and tastes great-kind of like a less sweet whipped cream.
1 c. heavy whipping cream
1/3 c. sour cream
1 T powdered sugar (I took matters into my own hands and did 3 T instead)
Whip until soft peaks form. Ta da!
