A rather unexpected kerfuffle blew up on my Facebook today after my wife put cream on the scone first and then followed it with jam. This, it seemed to me to be heresy. Jam gets much better traction on the dough and the cream sits on top. Images on flickr seem to be about 50/50 on the subject.
There was some talk of it being a Devon vs. Cornwall thing. Can these things really be that regional?
