8 tablespoons butter unsalted cut into 1/2-inch pieces (1 stick)
4 cups flour whole-wheat plus more if needed
Equipment
bowl
baking sheet
oven
pot
wooden spoon
Directions
Preheat the oven to 325°F.
Mix the flour, baking powder, and salt together in a large bowl.
Add the butter and use your fingers to pinch the butter and the flour mixture together; when it's all combined, it will resemble large bread crumbs.
Use a wooden spoon to mix in the brown sugar and raisins, and then add the buttermilk. If the dough is quite sticky, add more flour, 1 tablespoon at a time, until the dough has the texture of modeling clay. If it's too dry, add more buttermilk, 1 tablespoon at a time, until it's wet enough.
Turn the dough out onto a floured work surface and roll it out into a rectangle 1/4 inch thick.
Cut the dough into 12 (3-inch) squares. Leftover scraps can be rerolled to make more scones.
Oil a baking sheet. Fold each square of dough in half diagonally to form a triangle, and lay it on the sheet.
Bake the scones until the tops are golden brown, about 30 minutes.
Serve warm, with jam and a pot of hot tea if you like.
