This is a recipe I am still playing with. Check back in a couple days for an update.
2 cups all-purpose flour
1/2 cup cake flour (not self-rising)
1/4 cup granulated sugar
2 1/2 teaspoons baking powder
1 teaspoon cinnamon
1/4 teaspoon cloves
1/4 teaspoon ginger
1/8 teaspoon nutmeg
3/4 teaspoon salt
4 ounces (1 stick) cold unsalted butter, cut into small pieces
1 cup pumpkin
1/2 cup low-fat buttermilk
1 large egg, plus 1 large egg lightly beaten for egg wash
1/2 teaspoon pure vanilla extract
Fine sanding sugar, for sprinkling
1.Preheat oven to 375 degrees. Line a baking sheet with parchment paper.
2.Whisk together flours, granulated sugar, baking powder, spices and salt in a large bowl. Cut in butter with a pastry cutter, or rub in with your fingers, until mixture has the texture of coarse meal. Stir in pumpkin.
3.Whisk together buttermilk, 1 egg, and the vanilla. Drizzle over flour mixture, and stir lightly with a fork until dough comes together but a small amount of flour remains in bowl.
4.Turn out dough onto a work surface, and gently knead dough once or twice just to incorporate flour. Pat dough into a 12 inch rectangle. Cut into 12 wedges. Transfer to prepared baking sheet. Brush with egg wash, and sprinkle with sanding sugar. Bake until golden brown and cooked through, about 20 minutes. Transfer scones to wire racks to cool. Scones are best served immediately but can be frozen for up to 1 month. Thaw, and reheat in a 350-degree oven for 10 minutes.
