Servings

2.0
2 cup  white all purpose flour 0.25
0 1/4 cup  sugar 1.0
1 tsp  baking soda 1.0
1 tsp  cream of tartar 2.0
2 oz  crystallized ginger 2.0
2 tsp  grated lemon rind 1.0
1 cup  low fat buttermilk 1.0
1 tbsp  canola oil 1.0
1 each  Eggs, large, raw 1.0
1 tbsp  cold water 1.0
1 tbsp  sugar

1. Preheat oven to 350 F.
2. In a medium bowl, mix together flour, 1/4 cup sugar, baking soda, and cream of tartar. Stir in ginger and lemon zest.
3. In a small bowl, combine buttermilk and oil and add to the dry ingredients, stirring just until blended. Turn the slightly sticky dough out onto a lightly floured work surface and pat to 1/2-inch thickness. Using a floured, 4-inch round cutter, cut out the dough.
4. Cut each circle in half to make half-moons. Re-roll and cut the scraps, handling the dough as little as possible. Place scones onto a baking sheet that has been lightly coated with nonstick cooking spray.
5. In a small bowl, lightly beat the egg with the water. Brush the tops of the scones with the egg glaze. Sprinkle scones with 1 Tbsp of sugar.
6. Bake for 15 to 20 minutes, or until the tops are golden and firm to touch. Serve warm.
