At the risk of alienating 50% of you
This how I do mine
Cut a scone in half, on one half I put clotted cream and then jam, and on the other half I put jam and then clotted cream... Why you may ask... because I'm not a fan of putting the top half back on the scone... it just squirts out the sides when you bite into it. My way you get to honour both methods whilst getting twice as much jam and clotted cream.
I'm a frickin genius. :)
