Transfer to a lightly floured surface and knead dough gently four or five times and then pat the dough into a circle that is about 7 inches (18 cm) round and about 11/2 inches (3.75 cm) thick. Cut this circle in half, then cut each half into 3 or 4 pie-shaped wedges (triangles). Place the scones on the baking sheet. Make an egg wash of one well-beaten egg mixed with 1 tablespoon milk and brush the tops of the scones with this mixture.
04Bake for about 20 to 25 minutes or until golden brown and a toothpick inserted in the middle comes out clean. Remove from oven and then turn your broiler on high. Sift confectioners (powdered or icing) sugar heavily over the tops of the scones and place them under the broiler. Broil for just a few seconds, turning the pan as necessary, until the sugar has melted and turns golden brown. Make sure to watch the scones carefully as the sugar will burn very quickly. Transfer to a wire rack to cool.
