Ragù alla bolognese

Bolognese sauce,[a] known in Italian as ragù alla bolognese[b] or ragù bolognese , is a meat-based sauce in Italian cuisine, typical of the city of Bologna. It is customarily used to dress tagliatelle al ragù and to prepare lasagne alla bolognese. Italian ragù alla bolognese is a slowly cooked meat-based sauce, and its preparation involves several techniques, including sweating, sautéing and braising. Ingredients include a characteristic soffritto of onion, celery, and carrot, different types of minced or finely chopped beef, often alongside small amounts of fatty pork. White wine, milk, and a small amount of tomato paste or tomato sauce are added, and the dish is then gently simmered at length to produce a thick sauce.
