Preparation Steps

• Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper.
• In a large bowl, whisk together the flour, sugar, baking powder, and salt.
• Cut in the cold butter using a pastry blender or your fingertips until the mixture resembles coarse crumbs.
• Pour in the cold buttermilk and mix until just combined. Do not overmix.
• Turn the dough out onto a lightly floured surface and gently pat it into a 0.75-inch thick disc.
• Cut the disc into 8 wedges using a sharp knife or pizza cutter.
• Place the scones on the prepared baking sheet and brush the tops with the beaten egg.
• Bake for 15-18 minutes, or until golden brown and cooked through.
• Let cool slightly on the baking sheet before transferring to a wire rack.
