01 - Place potatoes in a saucepan, cover with cold water, and bring to a boil. Simmer for 10-12 minutes or until very tender. Drain well and mash until smooth; let cool slightly.
02 - Add butter and salt to the warm potatoes, mixing until fully incorporated.
03 - Sift in the flour and mix gently to form a soft, slightly sticky dough. Avoid overworking.
04 - Turn dough out onto a lightly floured surface. Shape into a round about 1/2 inch thick. Cut the round into quarters (farls).
05 - Heat a large nonstick skillet or griddle over medium-low heat. Lightly grease with butter.
06 - Cook the farls for 3-4 minutes per side, until golden brown and cooked through.
07 - Serve warm with extra butter or alongside a traditional Irish breakfast.
