Peel, wash and coarsely grate the potatoes and mix with egg, flour and salt. Fry approx. 8 flat buffers from the potato mixture in hot clarified butter until golden brown on both sides. Wash and dry the tomatoes and cut out the stalks. Cut the tomatoes into slices.
Drain mozzarella and cut into 8 slices. Cover each buffer with 1-2 tomato slices, 2 salami slices and mozzarella. Sprinkle with seasoned pepper and bake in the preheated oven (electric cooker: 200 °C/ gas: level 3) for about 5 minutes. Sprinkle with basil leaves
