Peel and wash potatoes. Grate in a food processor. Squeeze moisture out of potatoes. Place in a mixing bowl. Mix in the beaten eggs, flour, salt, pepper and grated onion.
Heat 2 tablespoons oil in a non stick frying pan. Spoon potato mixture in oil, the equivalent of 3-inch round pancakes.
Fry to a golden brown color on both sides.
Heat in oven before serving.
