Fill a saucepan 2/3 with water and bring to a boil.
Meanwhile, cut the gorgonzola into small cubes. Melt gently in a pan with the butter over low heat. Slowly add the cream and parmesan cheese, stirring constantly. Season to taste with salt and pepper.
Add a teaspoon of salt and the gnocchi to the boiling water. As soon as all the gnocchi have risen to the surface, take them out or pour them off and mix with the hot cheese cream. Serve immediately.
