How to Make It
Preheat the over to 425˚F. Soak the currants in buttermilk for 5 minutes.
Whisk together the flour, next 4 ingredients, and 2 tablespoon of the sugar. Cut in the butter with a pastry blender until the mixture is crumbly. Gradually add the currants and buttermilk, stirring just until dry ingredients are moistened. Turn the dough out onto a lightly floured surface, and knead lightly 2 or 3 times.
Pat the dough into an 8-inch (3/4 inch thick); cut into 8 wedges with a floured knife. Separate the wedges, and place on a parchment paper-lined sheet. Brush the scones with milk, and sprinkle with the remaining 1 ½ tablespoons sugar.
Bake at 425˚ F for 16 to 18 minutes or until lightly browned.
