01 - Place the peeled potato chunks in a large saucepan with salted water. Bring to a boil and cook until tender, about 12–15 minutes. Drain thoroughly and let steam dry for 2 minutes.
02 - Mash the potatoes until completely smooth. Add the butter and milk, mixing until creamy and free of lumps. Allow the mixture to cool for 5 minutes.
03 - Stir in the flour, salt, and pepper until a soft, slightly sticky dough forms.
04 - Turn the dough onto a lightly floured surface. Knead gently for 1–2 minutes, then pat into a disc approximately 1/2 inch thick.
05 - Use a 2 3/4 inch round cutter to cut circles, or slice into triangles.
06 - Heat a non-stick skillet or griddle over medium heat. Melt a small amount of butter to coat the surface.
07 - Cook in batches for 3–4 minutes per side until golden brown and crisp. Add more butter as needed between batches.
08 - Serve warm with butter, scallions, or as part of a full Irish breakfast.
