Ingredients:
- 2 cups (250g) all-purpose flour
- 1/3 cup (65g) granulated sugar
- 1 tbsp (12g) baking powder
- 1/2 tsp (3g) salt
- 1/2 cup (115g) unsalted butter (cold, cubed)
- 3/4 cup (180ml) buttermilk (cold)
- 1 cup (140g) fresh rhubarb (diced into 1/4 inch pieces)
- 1 large egg (cold, beaten)
- 1 cup (120g) powdered sugar
- 2 tbsp (30ml) fresh lemon juice
- 1 tsp (2g) lemon zest
Instructions:
- Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper.
- Dice the rhubarb into uniform 1/4-inch pieces. Pat the pieces dry with a paper towel if they are exceptionally juicy.
- Whisk together the all-purpose flour, granulated sugar, baking powder, and salt in a large mixing bowl.
- Add the cold, cubed butter to the dry mix. Use a pastry cutter or fork to work the butter in until the mixture resembles coarse crumbs with some pea-sized chunks remaining.
- Pour in the cold buttermilk and stir gently with a spatula just until the dough begins to clump.
- Gently fold in the diced rhubarb pieces, mixing only until distributed to avoid overworking the gluten.
- Turn the dough onto a lightly floured surface and pat it into a circle approximately 1 inch (2.5cm) thick. Cut the circle into 8 equal wedges.
- Place the wedges on the baking sheet with 1/4 inch of space between them and brush the tops with the beaten egg.
- Bake for 15–18 minutes until the edges are mahogany-colored and the tops are golden-brown.
- Whisk together powdered sugar, lemon juice, and lemon zest to create a glaze; apply to the scones once they have cooled slightly.
