01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
02 - In a large bowl, whisk together the flour, sugar, baking soda, baking powder, and salt until well blended.
03 - Stir in the dried currants, ensuring they are evenly distributed throughout the flour mixture.
04 - In a separate bowl, whisk together the buttermilk, egg, and melted butter until combined.
05 - Pour the wet ingredients into the dry mixture. Gently stir with a fork or spatula until a soft, slightly sticky dough forms. Do not overmix.
06 - Turn the dough onto a lightly floured surface. Pat into a 1-inch thick round. Cut into 8 wedges and arrange on the prepared baking sheet, spaced slightly apart.
07 - Brush the tops with buttermilk. Bake for 16 to 18 minutes until golden brown and a toothpick inserted into the center comes out clean.
08 - Cool slightly before serving. Enjoy warm or at room temperature.
