Preheat the oven to 375°F. Spray a muffin tin with nonstick spray.
In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt. With a pastry cutter or two knives used scissors fashion, cut in the butter until the mixture resembles coarse crumbs. (You can also do this part in a food processor and let the blades mix the flour and butter together). In a small bowl, stir together the buttermilk and egg until blended. Add the buttermilk mixture to the dry ingredients and stir to combine. Stir in the currants and caraway seeds (if using).
Spoon the batter into the prepared muffin cups. Bake 20 to 25 minutes, or until a cake tester inserted into the center of one muffin comes out clean.
Remove the muffin tin to a wire rack. Cool 5 minutes before removing the muffins from the muffin cups; finish cooling on a rack. Serve warm or cool completely and store muffins in an airtight container at room temperature.
Notes
*These muffins freeze well.
*Reader tip: Try using 1 cup of white flour and 1 cup of wheat flour- yum!
*Reader tip: Try subbing raspberries and blueberries for the currants (with no caraway seeds).
