Start by washing and peeling the potatoes and onion. Grate them finely and keep in a bowl.

In a mixing bowl, combine the grated potatoes and onion with salt and optional pepper. Add flour and egg, then mix until a cohesive batter forms.

Heat oil in a skillet over medium heat. Drop 2 tablespoons of batter for each pancake, flatten slightly, and cook for 3-4 minutes until golden brown.

Remove pancakes using a slotted spatula and drain on paper towels. Keep them warm in the oven if frying in batches.

Serve hot with apple sauce or savory dips like sour cream or yogurt.
