01 - Grate the potatoes and onion using the coarse side of a box grater or a food processor. Place the grated mixture in a clean kitchen towel and squeeze out as much liquid as possible.
02 - Transfer the mixture to a large bowl. Add eggs, flour, salt, pepper, and nutmeg (if using). Mix thoroughly until well combined.
03 - Heat the oil in a large nonstick skillet over medium-high heat until shimmering.
04 - Drop heaping tablespoons of the potato mixture into the hot oil, flattening gently with a spatula to form pancakes about 1/2 inch thick. Fry for 3–4 minutes per side until golden brown and crispy.
05 - Drain on paper towels and keep warm in a low oven while repeating with remaining batter. Serve hot with applesauce or sour cream.
