01 - In a large mixing bowl, sift together the flour, baking soda, and salt.
02 - Make a well in the center of the dry ingredients and pour in the buttermilk. Mix quickly with your hand or a wooden spoon to form a soft dough. Add a splash more buttermilk if the dough appears too dry.
03 - Turn the dough out onto a lightly floured surface. Gently knead just enough to bring it together, then pat it into a round approximately ¾ inch thick.
04 - Cut the round dough into four equal quarters, known as farls, using a floured knife.
05 - Heat a heavy-based skillet or griddle over medium-low heat. Lightly dust the surface with flour to prevent sticking.
06 - Place the prepared farls onto the hot griddle. Cook for about 7–8 minutes on each side, until they are golden brown and fully cooked through.
07 - Remove the farls from the pan and immediately wrap them in a clean tea towel for a few minutes. This step helps to keep them soft.
08 - Serve the soda farls warm, generously spread with softened butter.
