Start by preparing gnocchi.
Boil the potatoes and mash them while still hot. In a bowl, mix potatoes, a pinch of salt and flour a little at a time. Make a lump of dough and then loaves. Cut them into small pieces and slide them over a fork to give them the classic gnocchi shape.
Cook the gnocchi in plenty of salted water and drain them when they rise to the surface.
