4oz / 120ml sourdough discard (100% hydration)

• Line the scones onto the prepared baking sheet, leaving 1" space between. Brush the tops of the scones with buttermilk and sprinkle with Demerara or granulated sugar (sugar optional)
• Arrange oven racks in the upper and lower third of the oven, swapping and rotating the trays after 10 minutes (total baking time 15-20 minutes).
• The scones are ready when they are golden brown and sound hollow when the bottom is tapped.
