50 gr Butter
20 gr Grated Parmigiano-Reggiano cheese
50 gr Mozzarella
100 gr Parma ham
600 gr Potatoes
Salt and Pepper
Peel and boil the potatoes in salted water and mash them while still warm.
Before they have cooled down add the thoroughly beaten eggs, Parmesan cheese, a pinch of nutmeg, a knob of butter, salt and pepper. Knead into a dough and fill the slightly buttered molds with it and sprinkle with breadcrumbs.
Make a hole in the center with your thumb. Place in oven.
When finished take out of oven and fill the holes with small pieces of Parma ham and mozzarella.
