Soffritto

Soffritto is a combination of sautéed onions, celery, and carrots, and it is the base of much Italian cooking. We start many of our dishes by sautéing these ingredients, and then we have this, a very dark soffritto, that we cook for four hours, after which the vegetables are transformed into a rich, thick paste. We make the soffritto in big batches and use it as a starting point for many of our ragùs, such as the duck ragù (see Gnocchi with Duck Ragù, page 187), the wild boar ragù (see Maltagliati with Wild Boar Ragù, page 185), and the ragù bolognese (see Garganelli with Ragù Bolognese, page 189). We also use it to make a rich contorni—Yellow Wax Beans Stracotto in Soffritto with Salsa Verde (page 260)—that we serve in the Osteria. This soffritto might seem oily, but don’t let that scare you as it’s used to start dishes where olive oil would normally be used. At the restaurant, we chop the carrots and celery in a food processor, but we chop the onions by hand to avoid their becoming a watery purée.
