Whole wheat Irish soda bread

Instructions

1. Position a rack in the center of the oven and preheat the oven to 325°F.
2. Whisk the buttermilk and oil in a medium bowl; set aside.
3. Whisk 1 cup all-purpose flour, the whole-wheat flour, raisins, caraway seeds, baking soda, baking powder and salt in a large bowl. Stir in the buttermilk mixture with a wooden spoon until thoroughly moistened.
4. Dust a clean, dry work surface with the remaining 1 teaspoon flour. Turn the dough out onto work surface and knead for 30 seconds, just until it coheres. Shape into a round loaf about 6 inches in diameter and 1 inch high. Use a sharp knife or a new razor blade to cut an "x" about 1/2 inch deep in the top of the loaf.
5. Lightly spray a baking sheet with nonstick spray, place the loaf on it, and bake until lightly browned and crusty, about 45 minutes. Transfer to a wire rack to cool for at least 15 minutes before slicing into 8 pieces.
6. Serving size: 1 slice
