Sift the flour, sugar and salt into a mixing bowl. Add the sultanas if you are making fruit scones. Add enough milk to the sunflower oil and beaten egg to make up to 250 ml.Then add the wet ingredients to the dry mixture.Mix lightly until the mixture comes together and you have a soft but not sticky dough.
Turn it out on to a lightly floured surface and pat it slightly to a height of about 3 cm.
Cut into circles using a cookie cutter (do not twist the cookie cutter as this will stop them rising). Put the scones onto a baking tray.You can brush the tops with some of the milk/egg mixture but I prefer not to.
Bake for 12 - 15 minutes.
Cool on a wire rack. Then serve with strawberry jam and clotted cream.
