Bolognese sauce, known in Italian as ragù alla bolognese, is a meat-based sauce originating from Bologna, Italy. In Italian cuisine, it is customarily used to dress “tagliatelle al ragù” and to prepare “lasagne alla bolognese”. In the absence of tagliatelle, it can also be used with other broad, flat pasta shapes, such as pappardelle or fettuccine, or with short tube shapes, such as rigatoni or penne. Genuine ragù alla bolognese is a complex sauce which involves slow cooking using a variety of techniques, including sweating, sautéing and braising. Ingredients include a characteristic soffritto of onion, celery and carrot, different types of minced or finely chopped meat (generally bovine, including beef, and possibly pork, such as pancetta), wine and a small amount of tomato concentrate.
