I own that scone!/That scone is gone!: The Great Debate

[Pheesh]

You're wrong because then you have to fit the whole scone in your mouth. Now, this may be socially acceptable with say a donut, or similar it is not proper etiquette for eating a Scone. Scones are eaten in halves. As such you should not sandwich them together. Even putting the poor etiquette aside, you have encountered a trap. The trap being that if you do that, sandwich them together, you get less cream and jam per scone. That's simply the worst idea when it comes to eating a scone. Ok, so maybe not as bad as butter and hot gravy but I must say, it's close.

Ah, but that's when it gets clever!

You have a choice of eating the whole scone if you're not in polite company (scones should be small enough to fit in your mouth whole. If not, then they're too large).

Or, you can have one half with just jam, and the other with just clotted cream. You can eat them one at at a time, or alternate between a bite of jam scone and a bite of clotted cream scone.

The third option is that you can smush the two halves together so that the jam half gets clotted cream on it, and the clotted cream half gets jam on it. Then, you can separate them and you have two halves which have both jam and clotted cream on them.

You literally just made up the part about the scone having to be small, or someone had misinformed you. Baking competitions have measurements for these things and both halves of a 'perfect scone' would not fit classily into your mouth. If a scone is flat enough to do that then you've either cut it too small in diameter (tbf, Night Fury makes mini scones like that and they are smurfing delicious) or it hasn't risen enough in the baking process, meaning it'll be unusually dense.

Don't smurf with someone whose girlfriend makes him watch that much Great British/Australian Bake Off.
