Soda Water Scones

It doesn't seem too feasible for baking to be a type of cooking that can be considered super speedy- but scones are one of the few, and that's just regular ones. These however take the piss ever so slightly by being just three ingredients, and can probably be done with just a bit of extra spring in 15 minutes.
These scones don't need extra sugar, but if you wanted a bit of extra flavour and sweetness use lemonade as opposed to soda water. Bare in mind scones typically aren't sweet of themselves, it's what you spread them with that counts.
1)Combine 300g self raising flour with a pinch of salt and then pour in 150ml each double cream and soda water (make sure it's not flat) mix gently to a soft dough (you can add some sultanas at this stage if you like).
2)Pat it down to a thickness of a few inches and cut out rounds with a cutter- or just cut rectangles or triangles with a butter knife. Place on a baking sheet and glaze with milk then optionally sprinkle with demerara sugar.
3)Transfer to a preheated 180 degree oven and bake for about 10-12 minutes until quite golden but do them slightly less than you'd think they need, just to keep their belly nice and tender and not dry.
