01 - Boil the potatoes in salted water until fork-tender, about 12-15 minutes. Drain well and return to the hot pot to steam dry for 1-2 minutes.
02 - Mash the potatoes until smooth and lump-free. Allow to cool slightly.
03 - Add the softened butter, flour, baking powder, and ground white pepper to the mashed potatoes. Mix until a soft, non-sticky dough forms.
04 - Turn the dough onto a lightly floured surface. Gently knead just until combined, then shape into a flat round about 1/2 inch thick.
05 - Cut the round into quarters (farls).
06 - Heat a heavy skillet or griddle over medium heat and add a little butter or oil.
07 - Cook the farls for 3-5 minutes per side, until golden brown and slightly crispy.
08 - Serve warm, ideally with butter or as part of a traditional Irish breakfast.
