pre-heat oven to 200c, grease a baking sheet.
sift the flour , baking powder and salt together in a bowl.
Rub in the butter with your fingertips until the mixture resembles fine breadcrumbs, stir in the sugar.
Make a well in the centre and pour in a sufficient amount of milk to make a soft dough.
Turn out the dough onto a lightly floured work surface a knead lightly. Roll out to a thickness of about 1 inch. Don't be heavy handed , scones need a light touch . using a cutter or a floured glass (turned up side down) cut out 8 scones and put onto a prepared baking sheet. Brush each scone with the beaten egg + salt mix ,this will leave a shining glaze on top of baked scones.
Place into a pre-headed oven for 12 - 15 minutes until well risen and golden. Transfer to a wire rack and leave to cool.
