Start the oven on 250 degrees Celsius on electrical heat.
Mix the flour, baking powder and the salt in a big bowl.
Put the margarine in the bow and grind it together with the flour with your fingertips or a fork until it forms a crumbly dough. Continue until you don’t have any big butter lumps.
Add the milk in the bowl and stir it together in to a dough.
Divide the dough in 4 pieces. Form them on a baking paper in to round cakes approx 2 cm high.
Cut with a sharp knife a cross from one side to the other in the dough, but be careful not to cut all the way through.
Prick the dough with a fork.
Put the scones in the middle of the oven for 15 minutes, until they get a golden brown surface.
