I know you have been gone for sometime now, but we are well acquainted with scones in this country. At least, our version of it, which comes at us via Starbucks and other coffee shops. It's typically of a biscuit consistency but rather than savory it's more often than not sweet, and sometimes even glazed
BTW, American-style (southern) biscuits cannot be found here, anywhere. Not even the crappy canned ones.
I've had things called "scones" in America but they weren't quite the same.
[edit] To clarify - proper scones are nearly always savory. The only exception I've seen is when dates are used, adding some sweetness; but they are still primarily savory. A glazed scone is just wrong IMO, it's not a doughnut!
I wouldn't say plain (english) scones are savory. They're neutral like bread. A plain scone that you top with jam and cream isn't really savory. But you can just as easily use them the way Americans use biscuits because they aren't typically sweet either. Damn you, now I want scones.
