YIELD: 1 loaf
TOTAL TIME: 90 min
Preheat oven to 375 degrees F.
Combine the flour, sugar, baking soda, and salt. Add the butter and mix with an electric mixer with a paddle attachment on low speed until the butter is mixed into the flour like pie dough.
Mix the buttermilk and egg in a cup. On low, slowly add the buttermilk mixture to the flour mixture. Combine the raisins with 1 tablespoon of flour and mix into the dough.
Turn out dough onto a well-floured surface and knead it a few times into a loaf. Place the loaf on the prepared sheet pan and cut an X into the top.
Bake for 55 to 65 minutes. When you tap the loaf, it will have a hollow sound.
Serve warm or at room temperature.
