This is the prince of Genoese dishes. In Italian cuisine, pesto is considered the most important and the most famous of uncooked sauces. A true pesto, as the name indicates (it means ground or pounded), is made in a stone mortar with a boxwood pestle. With the development of food processors and blenders the tradition of the mortar is disappearing, especially in restaurants. If you wish to make the dish in the style of the Levantine Riviera (which runs between Genoa and the Cinque Terre with Camogli and Portofino in the middle), potatoes and green beans are served together with the pasta.
