Format similar to spaghetti but with a greater thickness and a square rather than a round section, which derives from the typical tool used for its preparation (called precisely “guitar”), which gives this pasta a strong texture capable of completely capturing the condiment, which can range from a simple but delicious tomato and basil, to a more full-bodied and rustic one such as sausage and radicchio to a more “healthy” one such as “Genovese pesto” Rustichella d'Abruzzo.
