Peel and grate the potatoes. Rinse under cold water until clear.

Drain grated potatoes using a clean kitchen towel to remove moisture.

In a bowl, combine drained potatoes with onion, salt, and pepper. Add optional seasonings if desired.

Heat oil or butter in a skillet over medium-high heat.

Form potato mixture into patties and fry for about 4-5 minutes per side until golden brown.

Transfer to paper towels to drain excess oil and serve hot.
