Turn the mixture out onto a floured surface and press it together so it sticks. Flatten it out to around 2/3-1in/2-3cm thick and cut out rounds, trying not to twist the cutter as you cut (around a 2 1/2in/6cm cutter is good but you can make smaller if you prefer). Carefully transfer the scones to the prepared baking sheet.
06Brush the top of the scones with the reserved egg and milk.
07Bake for around 10-12 minutes until gently brown on top.
