Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
In a large bowl, whisk together the flour, sugar, baking powder, and salt until well combined.
Add the cold cubed butter to the flour mixture. Using a pastry cutter or your fingers, work the butter into the flour until it resembles coarse crumbs.
In a separate bowl, mix the buttermilk and almond extract together.
Slowly add the buttermilk mixture into the flour mixture, stirring gently until just combined. Do not overmix.
Fold in the cherries and sliced almonds, ensuring even distribution throughout the dough.
Turn the dough out onto a floured surface and gently knead it a couple of times to bring it together. Pat it into a circle about 1 inch thick.
Cut the dough into 8 wedges and transfer them to the prepared baking sheet.
Brush the tops of the scones with the beaten egg for a golden finish.
Bake for 15-20 minutes, or until the scones are golden brown on top and a toothpick inserted into the center comes out clean.
Allow the scones to cool on the baking sheet for a few minutes before transferring them to a wire rack.
Notes
Dust with powdered sugar and serve warm with clotted cream or cherry jam.
