Clean the potatoes and cook in salted water for about 25-30 minutes. Drain and let cool down briefly. It is important that the potatoes are peeled while they are still hot.
Put the peeled potatoes in a mixing bowl and let them evaporate for 10 minutes. Mash finely with the potato masher and mix 2 teaspoons of salt, eggs, 150 g of flour and nutmeg with a fork.
Dust the work surface with the rest of the flour, knead the dough into a 3 cm thick roll. Cut into 1 cm thick slices with a knife and shape into oval gnocchi with your hands and place on a floured plate. Cook the gnocchi in portions in plenty of salted water and remove them with a sieve spoon as soon as they float on the surface.
Melt the butter and olive oil in a pan and fry the sage leaves until crispy. Add the gnocchi (in portions) and walnuts and toss in them for 3-4 minutes until they are lightly brown. Season to taste with salt and pepper. Keep the gnocchi warm until serving.
Tip 5: If you prepare the summer salad before searing the gnocchi, you can add the gnocchi directly to it and serve.
