01 - In a large mixing bowl, sift together the flour, baking soda, and salt.
02 - Make a well in the center and pour in the buttermilk. Mix quickly with your hand or a wooden spoon to form a soft dough. Add additional buttermilk if the dough appears too dry.
03 - Turn the dough out onto a lightly floured surface. Gently knead just to bring it together, then pat into a round approximately 0.75 inches thick.
04 - Cut the dough into quarters using a floured knife.
05 - Heat a heavy-based skillet or griddle over medium-low heat. Dust lightly with flour.
06 - Place the farls onto the hot griddle and cook for approximately 7 to 8 minutes on each side, until golden brown and cooked through.
07 - Remove from the pan and wrap in a clean tea towel for a few minutes to keep them soft. Serve warm, generously spread with softened butter.
