01 - Place potatoes in a saucepan and cover with cold water. Bring to a boil and simmer for 10-12 minutes until very tender. Drain thoroughly and mash until smooth. Allow to cool slightly.
02 - Add butter and salt to the warm mashed potatoes. Mix until completely incorporated and the mixture is smooth.
03 - Sift the flour into the potato mixture. Mix gently until a soft, slightly sticky dough forms. Be careful not to overwork the dough.
04 - Turn the dough onto a lightly floured surface. Shape into a round disk approximately 1/2 inch thick.
05 - Cut the round dough into four equal triangular quarters, known as farls.
06 - Heat a large nonstick skillet or griddle over medium-low heat. Lightly grease with butter.
07 - Place the farls in the heated pan and cook for 3-4 minutes per side until golden brown and cooked through.
08 - Serve warm with additional butter or as part of a traditional Irish breakfast.
