Mix in currants. Mix in egg and enough buttermilk to form soft dough. Turn dough out onto floured surface. Pat dough into 3/4-inch-thick round. Cut out rounds, using 2 1/2-inch round cookie cutter. Gather scraps, press together and pat out to 3/4-inch-thick round. Cut out additional rounds. Transfer scones to prepared baking sheet. Brush tops with milk.
