Combine dry ingredients in a large mixing bowl. Slowly add the buttermilk, stirring to combine, until you have a sticky dough.
Knead the dough lightly before transferring to a lightly greased baking sheet.
Shape the dough into a flattened round. Cut a cross into the top to release the fairies. (I was not aware that fairies live in bread dough but since I was instructed on this key step by an Irish baker, I'm sticking to it!)
Bake for approximately 40-45 minutes. Bread will be golden on top and offer a hollow sound when tapped when it is fully cooked.
Notes
It is important to use high-quality stone ground wheat flour to make this bread. My preference is the Bob's Red Mill brand.
