• Preheat oven to 425℉. Gather your ingredients so that you have everything close by on the table or counter.

Make the Biscuit Dough

• In a large bowl, combine all-purpose flour, granulated sugar, salt, baking powder, and baking soda.
• Using a pastry blending fork, cut in butter until coarse crumbs form.
• Add unfed sourdough starter, buttermilk, and dried blueberries. Stir until dough forms.

Form Biscuits and Bake

• Turn onto a lightly floured surface and knead 10-12 times. Roll into a circle to 1/2" thickness. Cut with a large biscuit cutter.
• Place biscuits a baking sheet lined with parchment paper or a silicone baking mat.
• Bake in preheated oven for 12-15 minutes or until golden brown. Remove from pan and cool on a wire rack. Makes 12-15 biscuits.
