Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper.

In a large mixing bowl, whisk together the flour, sugar, baking powder, salt, and cinnamon.

Cut in the cold butter until the mixture resembles coarse crumbs.

In a separate bowl, whisk together the milk, egg, and vanilla extract. Pour this into the dry ingredients and stir gently.

Fold in the raisins or currants, making sure they are evenly distributed.

Turn the dough out onto a floured surface and knead gently a few times.

Pat the dough into a 1-inch thick circle or rectangle and cut into wedges or rounds.

Place on the prepared baking sheet and bake for 15-20 minutes until golden brown.

Cool for 5 minutes on the baking sheet, then transfer to a wire rack.
