For the gorganzola sauce, cut the cheese into small cubes. Heat the olive oil and melt the cheese in it over moderate heat.
Mix well the sour cream and Cremefine and stir into the Gorgonzola, let everything simmer together on low heat.
Remove the sauce from the heat and stir in the egg (the sauce must not boil at this point or the egg will curdle in the sauce).
Season the gorganzola sauce with salt and pepper.
