01 - Preheat the oven to 375°F. Line a 12-cup muffin tin with paper liners or grease thoroughly with butter.
02 - In a large mixing bowl, whisk together the all-purpose flour, whole wheat flour, sugar, baking powder, baking soda, salt, and caraway seeds until uniformly blended.
03 - In a separate bowl, whisk the buttermilk, egg, and melted butter until completely smooth and well combined.
04 - Toss the dried currants with 1 tablespoon of flour in a small bowl, ensuring they are lightly dusted to prevent sinking during baking.
05 - Pour the wet ingredients into the dry ingredients. Fold gently with a spatula just until the flour disappears, being careful not to overmix as this will toughen the muffins.
06 - Fold the floured currants into the batter until evenly distributed throughout.
07 - Divide the batter evenly among the prepared muffin cups, filling each approximately three-quarters full.
08 - Bake for 16 to 18 minutes, or until a toothpick inserted into the center of a muffin emerges clean and the tops are golden brown.
09 - Allow the muffins to cool in the pan for 5 minutes, then transfer to a wire rack to cool completely before serving.
