1. Prepare Potatoes:
Peel and chop the potatoes, then weigh them for accuracy. Steam or boil the potatoes in a medium pot until tender, about 20-25 minutes.
2. Mash the Potatoes:
Drain the cooked potatoes and let them dry in a sieve for 5 minutes. While still hot, pass the potatoes through the sieve, ricer, or mash them to achieve a light, fluffy texture.
3. Form the Dough:
Stir in the flour, salt, pepper, and melted butter into the mashed potatoes. Mix until the dough forms a ball.
4. Shape the Farls:
Turn the dough onto a lightly floured surface and flatten it into an 8-inch round disc. Cut the disc into 6 pieces.
5. Cook the Farls:
Heat a large frying pan or skillet over medium heat and melt a generous knob of butter. Add the potato farls and cook for about 5 minutes on each side until golden brown and crispy on the outside, while remaining fluffy in the center.
6. Serve:
Serve the farls immediately while hot, as part of a traditional Irish breakfast or on their own.
