One of the best things we ate in Milan was a pasta dish at Rovello 18. Their Chitarra con Guanciale, Puntarelle, e Pecorino is a super simple pasta that really shines with the crispy, salty guanciale (cured pork cheek) and bitter notes of the puntarelle.  Puntarelle is a very seasonal vegetable that arrives in markets in the Spring. If you can’t find puntarelle, you could try different chicory. If you can't find guanciale, then you can use cured bacon or pancetta.
