Grate the peeled potatoes finely using a grater. Place the grated potatoes in a clean kitchen towel or cheesecloth and extract as much liquid as you can.

Combine the finely grated potatoes, finely grated onion, eggs, flour, salt, and black pepper in a mixing bowl. Stir thoroughly until all the ingredients are evenly incorporated.

Allow the mixture to rest for 15 minutes. This aids in the release of excess moisture from the potatoes, resulting in crispier pancakes.

Heat a generous amount of vegetable oil in a large frying pan over medium-high heat.

Take a spoonful of the potato mixture and carefully deposit it into the hot oil. Gently flatten it with the back of the spoon to create a pancake shape. You can prepare multiple pancakes simultaneously, but avoid overcrowding the pan.

Fry the pancakes for approximately 4-5 minutes on each side, or until they attain a golden brown and crispy texture. Adjust the heat as necessary to prevent burning.

Remove the cooked potato pancakes from the pan and place them on a plate lined with paper towels to eliminate excess oil.

Continue this process until all the potato mixture is utilized, adding additional oil to the pan as required.

Serve the potato pancakes while hot, optionally garnished with sour cream or applesauce.
