01 - Place potatoes in salted water and boil until tender, about 12–15 minutes. Drain well and allow to steam dry for 2 minutes.
02 - Mash potatoes until smooth. Add butter and milk; mix until creamy and lump-free. Let cool for 5 minutes.
03 - Stir in flour, salt, and pepper. Mix to form a soft, slightly sticky dough.
04 - Turn dough onto lightly floured surface. Gently knead for 1–2 minutes, then pat into a disc about 1/2 inch thick.
05 - Cut into rounds using a 2 3/4 inch cutter or slice into triangles.
06 - Heat non-stick skillet or griddle over medium heat and melt a little butter.
07 - Fry potato cakes in batches for 3–4 minutes per side, until golden brown and crisp. Add more butter as needed.
08 - Serve warm, ideally with butter, scallions, or alongside a full Irish breakfast.
