Sourdough Scones

Step 1
Preheat an oven to 400 degrees F (200 degrees C). Line a baking sheet with parchment paper.

Step 2
Whisk together the flour, salt, cream of tartar, baking soda, sugar, and apple pie spice in a mixing bowl. Cut in the butter with a knife or pastry blender until the mixture resembles coarse crumbs. Add the sourdough starter and mix by hand to form a soft dough.

Step 3
Turn the dough out onto a lightly floured surface and divide it into 4 pieces. Pat or roll one piece of dough into a 1/2-inch thick round. Cut it into 4 wedge-shaped pieces and place the scones on the prepared baking sheet about 1 inch apart. Repeat with remaining pieces of dough. Brush the tops of the scones with milk and sprinkle with coarse sugar, if desired.

Step 4
Bake until the scones just start to turn golden, 12 to 15 minutes.
