01 - Place the peeled and cubed potatoes in a saucepan. Cover with cold water and add a pinch of salt. Bring to a boil, then simmer for 10–12 minutes or until fork-tender. Drain well and return to the pan for 1 minute to steam dry.
02 - Mash the potatoes thoroughly until smooth. Add the unsalted butter and milk while the potatoes are still hot, mixing well until the butter has melted and the mixture is creamy.
03 - Stir in the flour and salt. Mix until a soft, non-sticky dough forms. If too sticky, add a little extra flour.
04 - Turn the dough onto a lightly floured surface. Gently knead, then shape into a round about 1/2 inch thick. Cut the round into quarters (farls).
05 - Heat a non-stick frying pan or griddle over medium-low heat. No oil needed.
06 - Cook the farls in batches for 3–4 minutes per side, until golden brown and slightly puffed.
07 - Serve warm, generously spread with salted butter.
