Ingredients
  

  • 2 cups all-purpose flour
  • ½ cup sugar
  • 1 Tbsp baking powder aluminum-free
  • ½ tsp salt
  • 8 Tbsp unsalted butter frozen and then grated
  • 1 cup blueberries
  • 1 Tbsp fresh lemon zest about the zest of one lemon
  • ½ cup sourdough starter active or discard
  • 1 egg + 1 egg yolk cold
  • 1 tsp vanilla
  • 1 Tbsp milk cold + more if needed

Topping

  • 2 Tbsp heavy cream cold
  • 2 tsp sugar

Instructions
 

  • Combine the flour, sugar, baking powder, and salt in a large mixing bowl and whisk together.
  • Add the grated frozen butter, toss in the flour mixture, and then use your hands to break up the butter into pea size pieces.
  • Add the blueberries and lemon zest and toss to distribute evenly.
  • Make a well in the center of the dry ingredients, and in the well, add the sourdough starter, egg and egg yolk, vanilla, and milk. Mix the wet ingredients together and then stir them in with the dry ingredients until just combined, avoiding overmixing.
  • Shape the scone dough into an 8-inch round disk. Cut it into eight equal pie-shaped pieces, place on a parchment-lined baking sheet. Brush the tops of the unbaked scones with heavy cream and sprinkle with sugar.
  • Cover the scones (with plastic wrap or something air-tight) and allow to ferment in the refrigerator for 8-72 hours.
  • When ready to bake, preheat the oven to 400 degrees Fahrenheit. Remove the baking sheet from the refrigerator, uncover the scones, and bake for 20-25 minutes, or until lightly golden on the tops and edges. Remove and allow to cool for 5 minutes.

Notes

Don’t overmix the dough – Overmixing scone dough can develop more gluten than you need, resulting in a tough or dense scone.
 
Chill before baking – Chilling helps the scones not spread too much.
 
Adjust milk if needed – Depending on the moisture content of your sourdough starter, you may need to adjust the amount of milk, one tablespoon at a time.
 
Cheese grater – Use a cheese grater to get the frozen butter in the right size pieces.
