1 In a large mixing bowl combine flour, brown sugar, baking powder, ginger, baking soda, salt, and cinnamon. Using a pastry blender, cut in butter or margarine until mixture resembles coarse crumbs. Make a well in the center of the dry mixture.
2 In a small mixing bowl stir together the egg yolk, molasses, and milk. Add molasses mixture all at once to the dry mixture. Using a fork, stir until combined (mixture may seem dry).
3 Turn dough out onto a lightly floured surface. Quickly knead dough by gently folding and pressing for 10 to 12 strokes or until nearly smooth. Pat or lightly roll dough to a 7-inch circle. Using a knife, cut into 8 wedges. Arrange wedges on an ungreased baking sheet about
1 inch apart. Brush wedges with egg white. If desired, sprinkle wedges with coarse sugar.
4 Bake in a 400° oven for 12 to 15 minutes or until light brown. Transfer to a wire rack; cool for 20 minutes.
