DD's Scone Recipe (thank you Delia Smith)

As requested here is the scone recipe:
225g/8oz self raising flour
40g/1.5oz butter, at room temperature
1.5 tablespoons caster sugar
a pinch of salt
150ml/5 fl oz milk
a little extra flour

Pre-heat the oven to gas 7, 425 degrees F, 220 degrees C
Grease a baking sheet.
Sift the flour into a bowl and rub the butter into it rapidly, using fingertips (washed first please DD ;-) ). Stir in the sugar and salt, then using a knife, mix in the milk little by little. Flour your hands a little and knead the mixture to a soft dough - adding a drop more milk if it feels dry.
Turn the dough out onto a floured surface and roll it out to a thickness of not less than 3/4 inch (2cm). Take a 1.5" or 2" pastry cutter (DD used an egg cup), and cut out as many scones as you can, knead the dough trimmings together again and repeat until you have used it all.
Place them on the baking sheet, dust each one with a little extra flour and bake near the top of the oven for 12-15 minutes. When cooked the scones will have turned a crisp golden-brown. ENJOY!!!!
