Cook pasta by instruction on the package. While it cooks, put butter and cooking cream in a pan, add 1 dl of hot pasta water and stir. Season it with little salt, black pepper and pinch of nutmeg. Cook for a minute.
Then add Gorgonzola and grated hard cheese and stir until smooth. Finally add chopped basil leaves.
Drain pasta (save some water for later) and add it to the sauce. If it gets too thick just add a bit more pasta water.Serve hot.
