1 2/3 cups bread flour, plus more for dusting
1 1/3 cups whole wheat flour
1 1/4 teaspoons baking soda
1/2 teaspoon salt
1 1/2 cups buttermilk
1 large egg
1 teaspoon honey
Preheat the oven to 375°F. Line a baking sheet with parchment paper and sprinkle with a little bread flour; set aside.
Combine the flours, baking soda, and salt in a mixing bowl. In a separate bowl, measure out the buttermilk and then whisk in the egg and honey.
Make a well in the center of the dry ingredients, and then pour in the wet mixture. Using a wooden spoon, bring the mix together to form a dough. Add a little extra flour if you find the dough is too wet and sticky.
Turn the dough out onto a lightly floured work surface and sprinkle lightly with flour. Form the dough into a ball, then shape it into a round, about 6 inches in diameter.
Transfer the round onto the prepared baking sheet. Using a sharp knife, cut an "X" about 1/2-inch deep from end to end. Sprinkle lightly with more flour.
Bake in the oven for 35 minutes. The bread is cooked when the bottom is tapped and sounds hollow. Remove to a wire rack and cool before slicing and enjoying with a little butter.
