Place the eggs in a medium pot and cover with cold water by 1 inch. Bring to a boil over medium-high heat; boil for 30 seconds then remove from the heat, cover, and let stand for 15 minutes. Drain the eggs and run under cold water until cool. Carefully peel the eggs and halve each lengthwise. Carefully remove and reserve the yolks.
Peel the potatoes and grate them lengthwise. Place them in a colander or kitchen towel and squeeze out as much liquid as possible. Combine the potatoes in a bowl with the egg, flour, salt, and pepper. Mix well. Melt 2 tablespoons of clarified butter in a skillet.
