• Preheat Oven:Preheat oven to 425°F (220°C) and line a baking sheet with parchment paper.
• Mix Dry Ingredients:In a large bowl, whisk together the flour, baking powder, baking soda, salt, and sugar (if using).
• Cut in Butter: Cut the butter into cubes or use a box grater to shred the butter. Add the cold butter to the flour mixture. Using a pastry cutter or your fingers, work the butter into the flour until the mixture resembles coarse crumbs.
• Add Wet Ingredients: Stir in the sourdough starter and milk until just combined. The dough should be slightly sticky but manageable.
• Roll and Cut: Roll the dough to about 1-inch thick. Use a biscuit cutter or a glass to cut out biscuits, placing them on the prepared baking sheet. Gather any scraps and re-roll to cut additional biscuits.
• Bake: Bake in preheated oven for 14-15 minutes, or until the biscuits are golden brown.
• Cool and Serve: Remove from the oven and let cool slightly before serving. Enjoy warm with butter, jam, or your favorite topping!

Long Fermentation for Flaky Biscuits

• Cut the cold butter into small cubes, then add it to a large bowl.
• Mix the flour in with the butter.
• Use your hands to work the butter into the flour until the mixture starts to come together in a ball.
• Add the sourdough starter, sugar (optional), and milk or buttermilk to the bowl.
• Stir until everything is well combined.
• Cover the bowl with a clean tea towel or plastic wrap and let it sit at room temperature for at least 8 to 24 hours.
• The next day, incorporate the baking soda, baking powder, and salt into the fermented dough.
• Mix thoroughly to ensure even distribution.
• Roll out the dough on a lightly floured surface. Use a circular cookie cutter to cut out your biscuits.
• Place the biscuits in a well-seasoned cast iron skillet or a glass baking dish.
• For added height, let the biscuits rise in a warm place for 30 minutes to an hour before baking.
• Bake the biscuits in a preheated 400°F (200°C) oven for 14 to 15 minutes, until golden brown.
