Preheat oven to 200°C.
Sift the dry ingredients together.
Rub butter into dry ingredients with fingertips until mixture resembles breadcrumbs.
Beat the egg and milk together.
Make a hollow in the centre of the dry ingredients and gradually add liquid until a soft dough is formed.
Do not discard remaining liquid.
Lightly press dough out onto a lightly floured surface and cut into rounds with a sharp knife or cookie cutter.
Brush tops with remaining egg and milk mixture and bake for 12 - 15 minutes or until a skewer comes out clean when inserted into scones.
Break scones in half and serve with butter, jam and cream.
