01 - In a large mixing bowl, sift together the flour, baking soda, and salt.
02 - Create a well in the center of the dry ingredients and pour in the buttermilk. Mix quickly with your hand or a wooden spoon until a soft dough forms. Incorporate additional buttermilk sparingly if the dough appears too dry.
03 - Transfer the dough to a lightly floured surface. Gently knead just enough to unify the dough, then pat it into a round approximately ¾ inch thick. Using a floured knife, divide the dough into four equal farls.
04 - Heat a heavy-based skillet or griddle over medium-low heat. Lightly dust the cooking surface with flour.
05 - Place the farls onto the hot griddle and cook for about 7-8 minutes per side, until they achieve a golden brown color and are thoroughly cooked.
06 - Remove the cooked farls from the pan and immediately wrap them in a clean tea towel for a few minutes to maintain their softness.
07 - Serve the farls warm, generously spread with softened butter.
