01 - Wrap the grated raw potatoes in a clean kitchen towel and squeeze firmly to extract as much liquid as possible. This step is crucial for achieving crispy pancakes.
02 - In a large mixing bowl, combine the squeezed grated potatoes, mashed potatoes, sliced scallions, and melted butter. Stir until evenly incorporated.
03 - In a separate bowl, whisk together the flour, baking powder, salt, and black pepper until well blended.
04 - Add the dry ingredient mixture to the potato bowl. Pour in the milk and stir gently just until a thick batter forms. Avoid overmixing to prevent tough pancakes.
05 - Heat 1 tablespoon of vegetable oil in a large nonstick skillet over medium heat until shimmering.
06 - Scoop approximately 1/4 cup of batter per pancake into the skillet. Gently flatten with a spatula to form even rounds. Cook for 3-4 minutes on each side until golden brown and crispy. Add more oil between batches as needed.
07 - Transfer finished pancakes to a paper towel-lined plate to absorb excess oil. Serve immediately while hot, optionally garnished with additional sliced scallions.
