Peel and wash the potatoes and cook in salted water for about 20 minutes. Melt 1 tablespoon butter. Grate half of the Parmesan cheese. Mix with ricotta, eggs, approx. 1/2 tsp salt, 150 g flour and liquid butter. Drain the potatoes and press them through a potato ricer or mash them finely.
Stir the puree into the ricotta dough, cover and chill for about 30 minutes.
Dust a tray with flour. Form gnocchi from the very soft dough with two tablespoons, place on the tray, cover and chill for about 1 hour.
Bring plenty of salted water to the boil in a wide saucepan. Cook the gnocchi in portions for about 4 minutes at low heat. Remove with a skimmer and drain well.
Meanwhile wash parsley, shake dry and chop finely. Peel garlic and chop very finely. Heat 5-7 tablespoons of butter in a large frying pan. Sauté the garlic briefly. Add the gnocchi and fry for about 8 minutes, turning carefully.
Season to taste with salt and nutmeg. Sprinkle parsley over it and toss gnocchi in it. Serve everything. Slice the rest of the Parmesan cheese on top. Serve with a green salad.
