06 - Turn dough onto lightly floured surface. Gently pat into a 1-inch thick circle.
07 - Cut dough into 8 wedges. Arrange on prepared baking sheet with space between each piece.
08 - Brush tops with milk. Sprinkle with coarse sugar if desired.
09 - Bake for 16-18 minutes until scones are set and lightly golden at the edges.
