01 - Place potato chunks in salted water and boil 10–12 minutes until fork-tender. Drain thoroughly and mash until smooth. Allow to cool slightly.
02 - Wrap grated raw potatoes in a clean kitchen towel and squeeze firmly to remove excess moisture.
03 - In a large mixing bowl, combine mashed potatoes, grated potatoes, scallions, milk, melted butter, flour, baking powder, salt, and pepper. Stir until fully incorporated into a thick batter.
04 - Warm a large nonstick skillet or griddle over medium heat. Add a small amount of butter to coat the surface.
05 - Drop 2–3 tablespoons of batter per pancake into the pan, gently flattening with a spatula. Cook 3–4 minutes per side until golden brown and crisp. Cook in batches, adding butter as needed.
06 - Transfer cooked pancakes to a serving plate and keep warm while completing remaining batches. Serve immediately with optional toppings.
