Are English scones savoury?
They are both sweet and savoury.

You can use the same recipe &amp; put clotted cream &amp; jam on them, or butter [salted, of course], or slices of cheese, ham, anything you like… even Marmite. 

This is what you get searching the BBC [good old Auntie Beeb, can't get more stiff-upper-lip British ;) - BBC Good Food - Savoury scone recipes  Because I specifically searched 'savoury' these tend to not include sugar - but there's no reason at all that they can't.

There's a particular tang to those foods which fall perfectly between the two stools… pancakes &amp; crêpes are the obvious ones. There are British biscuits [cookies] that embody this sweet/salt dichotomy, even though they are in themselves considered 'sweet'. I'm thinking of the traditional Scottish shortbread &amp; the modern pretender, the Hob Nob. Heck, over here we even put cheese on xmas cake ;)
This sweet/salt is not the same as sweet &amp; sour, but a similar effect, I guess.
