Bolognese sauce, recognized in Italian as ragù alla bolognese or ragù bolognese (in Bologna just ragù; Bolognese dialect: ragó), is the primary variety of ragù in Italian food, typical of the city of Bologna. Ragù alla bolognese is a gradually cooked meat-based sauce, and its preparation involves several strategies, consisting of sweating, sautéing, and braising. Ingredients consist of a characteristic soffritto of onion, celery, and carrot, and different sorts of minced or carefully chopped beef, commonly along with percentages of fatty pork. White wine, milk, and a small amount of tomato paste or tomato sauce are added, and the dish is then carefully simmered at length to produce a thick sauce. Ragù alla bolognese is customarily utilized to clothe tagliatelle al ragù and to prepare lasagne alla bolognese. Outside Italy, the phrase "Bolognese sauce" is commonly used to refer to a tomato-based sauce to which minced meat has been included; such sauces generally bear little resemblance to Italian ragù alla bolognese, being more comparable as a matter of fact to ragù alla napoletana from the tomato-rich south of the country. Although in Italy ragù alla bolognese is not used with spaghetti (but instead with flat pasta, such as tagliatelle), in Anglophone countries, "spaghetti bolognese" has actually become a preferred meal.
