Peel the potatoes and grate them on a box grater. Wrap the grated potatoes in a 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 the clarified butter in a large saute pan over medium heat.
Place a tablespoon of the potato mixture into the sizzling butter and cook for 2 minutes. Turn the pancakes over and cook for another 2 minutes, or until crisp on the outside and golden brown.
