Peel and cut potatoes into thin slices or small pieces (or grate them). If you like, you can add the clove of garlic at this point and boil it with the potatoes. Place the sliced potatoes in a large amount of water (at least 2:1). Drain off the water and add a large amount of fresh water. Bring the water to a boil again and cook until the potatoes are soft and tender. Discard the cooking water.
Mash and let cool before adding the onion, chives, garlic (if you didn’t already add it), pepper and egg. Blend together and then form the potatoes into 8 pancakes.
Heat 2 tablespoons of the olive oil in a frying pan and then add 4 of the pancakes. Once they are golden and crispy on one side, flip the pancakes over. When they are done, remove them, and repeat with the 2 tablespoons of oil and the remaining 4 pancakes.
