Follow the instructions to double boil the potatoes according to this recipe.
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.
