Doesn't matter, scone is just a mechanism to transfer jam and clotted cream to my mouth.
Spoonful of each somewhere on the scone is fine. Usually the one on first is the one with the spoon instantly available... dh will also be spooning cream and jam on a scone, so we do opposites.
Usually put a spoon of jam and one of cream next to each other on one half of the surface, scarfe down that bit, then go for the spoons again...
