Orange and Dark Choclate Buttermilk Scones

1 1/2 cups all-purpose flour

2 tablespoons granulated sugar

2 teaspoons orange zest

2 1/4 teaspoon baking powder

1/4 teaspoon baking soda

1/2 teaspoon salt

6 tablespoons cold unsalted butter

1 large egg yolk

1/4 cup plus 2 tablespoons cold buttermilk

1/2 cup dark chocolate chips

1. Place rack in the upper third of the oven and preheat to 425 degrees F. Line a baking sheet with parchment paper and set aside.

2. In a mixing bowl, sift together flour, sugar, orange zest, baking powder, baking soda and salt. Cut in butter until mixture resembles coarse meal. I use my fingers to rub the butter and dry ingredients together.

3. In another bowl, combine egg yolk and buttermilk and beat lightly with a fork. Add to flour mixture all at once, stirring enough to make a soft dough. Fold in the chocolate chips.

4. Turn out onto a floured board and knead about 15 times. Roll or pat out into a 1-inch thickness. Cut into 4 large or 6 small squares. Place on prepared baking sheet and bake at 425 degrees F for 12-15 minutes. These are best when served immediately with butter and jam!
