01 - Preheat 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 all-purpose flour, whole wheat flour, sugar, baking powder, baking soda, salt, and caraway seeds until evenly blended.
03 - In a separate bowl, whisk buttermilk, egg, and melted butter until fully combined and smooth.
04 - Toss dried currants with 1 tablespoon flour in a small bowl, coating evenly to prevent sinking during baking.
05 - Pour wet ingredients into dry ingredients. Fold gently with a spatula just until flour disappears—do not overmix.
06 - Add floured currants to batter and fold in gently until evenly distributed throughout.
07 - Divide batter evenly among prepared muffin cups, filling each approximately three-quarters full.
08 - Bake for 16 to 18 minutes until golden brown and a toothpick inserted into the center comes out clean.
09 - Let muffins cool in pan for 5 minutes, then transfer to wire rack to cool completely.
