Stringozzi
Rough and thick, so it holds an oily truffle paste or a garlic and tomato sauce without help. Heavy enough for a sausage ragu.
Tonnarelli
A porous square strand grips a cheese emulsion like nothing else, which is why Roman trattorias serve tonnarelli cacio e pepe. It also takes lamb ragu in Abruzzo and a light seafood sauce on the coast.
