Preheat oven to 220C/425F/Gas 7. Grease a baking tray or line with baking paper. Sift the flour and baking powder into a bowl. Using your fingertips, rub in the butter until it resembles fine breadcrumbs. Stir in the sultanas and make a well in the centre.

Add the milk and mix using a cutting action until the dough comes together in clumps. With floured hands, gather the dough together, lift onto a lightly floured surface and pat into a smooth ball. Do not knead or the scones will become tough.

Pat the dough out to 2cms thick. Cut into rounds using a 5cm cookie cutter. Gather the trimmings and repeat. Place rounds close together on the baking tray and brush with a little milk. Bake for 12-15 minutes or until risen and golden brown.
