01 - Preheat oven to 425°F. Line a baking sheet with parchment paper or dust lightly with flour.
02 - In a large mixing bowl, whisk together the flour, baking soda, and salt until thoroughly blended.
03 - Create a well in the center of the dry ingredients. Pour in the buttermilk and stir gently with a wooden spoon just until a shaggy, sticky dough forms.
04 - Turn the dough onto a lightly floured surface. Gently knead briefly just until it holds together, avoiding overworking. Shape into a round, slightly flattened loaf approximately 2 inches thick.
05 - Place the loaf on the prepared baking sheet. Use a sharp knife to cut a deep cross shape across the top. Bake for 30-35 minutes until golden brown and the bottom sounds hollow when tapped.
06 - Transfer the bread to a wire rack and allow to cool for at least 30 minutes before slicing to ensure proper texture.
