Start with the Parmesan cream. Grate the cheese. Heat the milk and cream in a saucepan and add the grated cheese a little at a time. Continue stirring over low heat until melted. You will obtain a super creamy and velvety cheese fondue, perfect for accompanying Nonna Rina ravioloni. Cut half of the bacon into small pieces and brown it in a pan. Do the same with the remaining whole slices, which will be used for garnish.
Now it's time for the stars of the recipe: Nonna Rina's porcini and stracchino ravioloni. Drop them into plenty of boiling salted water, wait for them to float to the surface and drain them directly into the saucepan with the Parmesan cream.
Add the chopped bacon and sauté the ravioloni for a few moments to blend all the flavors, then plate. Serve drizzled with the Parmesan cream, garnished with the crispy bacon and a few shavings of Parmesan cheese. A sprinkling of pepper and voilà, bon appétit!
