Ingredients:
- 2 ½ cups All-Purpose Flour (plus extra for dusting)
- ½ cup Granulated Sugar
- 1 Tbsp Baking Powder
- 1 tsp Kosher Salt
- 8 Tbsp Unsalted Butter, very cold, cut into ½-inch cubes
- Zest of 2 large lemons
- ¾ cup cold Buttermilk
- 1 large cold Egg, lightly whisked
- 1 cup Fresh or Frozen Blueberries (do not thaw)
- 1 cup Sifted Powdered Sugar (for glaze)
- 2 – 3 Tbsp Fresh Lemon Juice (for glaze)
Instructions:
- Preheat the oven to 400°F (200°C/Gas Mark 6). Line a baking sheet with parchment paper.
- In a large bowl, whisk together the flour, sugar, baking powder, and salt. Add the lemon zest and rub it into the flour using your fingers until the mixture is fragrant.
- Add the very cold, cubed butter to the dry mixture. Use a pastry blender, two knives, or fingertips to quickly cut the butter into the flour until the mixture resembles coarse breadcrumbs, with some pea-sized pieces remaining.
- In a separate small bowl, lightly whisk together the cold buttermilk and the egg. Pour the wet mixture into the dry ingredients and mix only until the dough just comes together into a shaggy mass. Do not overwork the dough.
- Gently fold in the fresh or frozen blueberries.
- Turn the dough out onto a lightly floured surface. Pat it into a thick disc, about ¾-inch to 1-inch (2 cm) thick. Cut the disc into 12 equal wedges using a sharp knife or bench scraper.
- Arrange the scones on the prepared baking sheet. Place the tray in the freezer or refrigerator for a minimum of 15 minutes. (This chilling step is vital for ensuring a high rise.)
- Optional: Before baking, brush the tops lightly with a little extra buttermilk or an egg wash for shine. Bake for 18–20 minutes, or until the scones are deeply golden brown.
- Remove the scones from the oven and let them cool on a wire rack for 5–10 minutes.
- Prepare the Glaze: Whisk the powdered sugar and 2 tablespoons of lemon juice until smooth. Add the remaining tablespoon of juice gradually until the glaze reaches a thick, drizzling consistency.
- Drizzle the glaze generously over the warm scones. Serve immediately.
