Peel the potatoes and grate them into a large bowl filled with cold water, adding a few ice cubes to keep the water chilled.

Grate the onion into the bowl with the potatoes, combine, and let the mixture sit for 5-10 minutes.

In a separate bowl, whisk together the eggs, flour, and seasoning. Adjust the seasoning according to your taste.

Drain and rinse the potato-onion mixture thoroughly, then squeeze out excess water with a clean kitchen towel.

Gradually mix the potato mixture into the wet mixture, ensuring everything is well-coated.

Heat oil in a skillet over medium heat. Spoon the batter into the skillet to form pancakes of your desired size.

Cook the pancakes for 3-5 minutes on each side until golden brown, adding more oil to the pan as needed.

Serve hot with sour cream and chives or your preferred toppings.
