How to Make It
Preheat oven to 375°F.
In a medium bowl, stir together the flour, sugar, caraway seed, and 2 teaspoons salt. Stir in the raisins and the buttermilk until a dough forms. Transfer the dough to a floured surface and knead for 6 minutes. Form the dough into a disk and transfer to a parchment-lined baking sheet. Using a sharp knife, cut an X into the dough, then brush with the butter.
Bake the bread until golden and hallow-sounding when tapped, about 40 minutes. Let the bread cool completely, about 2 hours, then serve.
