01 - Preheat oven to 375°F. Line a 12-cup muffin tin with paper liners or grease thoroughly.
02 - In a large bowl, whisk together all-purpose flour, whole wheat flour, sugar, baking soda, baking powder, and salt until evenly distributed.
03 - In a separate bowl, whisk together buttermilk, egg, and melted butter until fully incorporated and smooth.
04 - Pour the wet ingredients into the dry ingredients. Fold gently with a spatula just until combined; stop mixing as soon as no dry streaks remain.
05 - Fold in dried currants and caraway seeds until evenly distributed throughout the batter.
06 - Divide batter evenly among prepared muffin cups, filling each about three-quarters full.
07 - Bake for 16 to 18 minutes until golden brown and a toothpick inserted into the center comes out clean.
08 - Let muffins rest in the tin for 5 minutes, then transfer to a wire rack to cool completely.
