Heat the cream in a saucepan and melt the Gorgonzola in it. Season to taste with a dash of white wine, nutmeg and pepper. Add the walnuts and let them steep.
Chop the shallot very small and slice the garlic. Let it turn to glass in a pan in walnut oil. Add the pumpkin cubes and, possibly with a little water, simmer until soft. Season with salt and pepper and refine with a piece of butter and nut oil.
Cook the pappardelle, arrange on plates, spread the pumpkin pieces on top and pour the Gorgonzola sauce over them.
Visually a great contrast, the light pasta, the orange pumpkin and the slightly bluish sauce.
