To serve:
In a mixing bowl, rub the flour, butter and salt together.
Stir the sugar in and then gradually add the milk to create a soft dough. If you need, add a little more milk.
Turn out onto a floured surface and work together with your hands gently. Work to a round of roughly 2cm thickness.
Cut out rounds with a cutter, and transfer to a baking sheet. Bring together remaining dough and repeat the process until it’s all used up.
Brush the tops of the scones with the egg wash, before transferring to a pre-heated oven at 220c (200c fan) for 12 to 15 minutes until the tops are golden.
Remove from the oven and transfer to a wire rack to cool before splitting and serving with preserve and clotted cream
