Spaghetti al soffritto is an ancient Neapolitan specialty, made with spaghetti (although other similar pasta, like bucatini, can also be used) and pork offal. Soffritto refers to a rich and hearty sauce made from a mixture of offal, commonly from pork, including parts like the lung, trachea, heart, spleen, and liver.
These are slowly cooked with tomato concentrate, chili pepper, and other seasonings until tender and infused with flavor. The resulting sauce is savory, with a balance of sweetness from the slow cooking process and acidity from the tomatoes. When served with spaghetti, it reflects the resourcefulness of Neapolitan cuisine, which often utilizes all parts of the animal.
