Instructions:
Combine dry ingredients; cut in butter until crumbly. Add buttermilk and egg, stir until moistened. Turn dough onto lightly floured surface and knead 5-6 times. Divide dough in half, roll each portion into a 6-inch circle. Cut each circle into 8 wedges and place 1 inch apart on lightly greased baking sheet. Bake at 425 degrees for 12-15 minutes or until golden brown. Combine 1 1/2 tablespoons fresh lemon juice with 1 cup powdered sugar and drizzle over warm scones.
