Pastries served with clotted cream (6)
I believe the answer is:
scones
(Other definitions for scones that I've seen before include "Small unsweetened or lightly sweetened cakes" , "Small soft cakes of flour, fat and milk - eaten buttered" , "Rich biscuit-like pastry, best served with jam and butter" , "Small cakes made with flour, fat and milk" , "Small plain cakes" .)
