This is a new version of the old kitchen recipe “little spaghettini with pork fat, pepper and pecorino cheese”; for a long time butter has been a food for rich people and used by the people living in Naples only on special occasions.If you want a more tasty dish, instead of cooking capellini in salted water, cook them in a good meat broth or vegetable broth and then flavour how described in the recipe whit butter, basil, pepper and parmigiano.
