Bolognese sauce (ragù alla bolognese in Italian, also known by its French name sauce bolognaise) is a meat based sauce for pasta originating in Bologna, Italy. Bolognese sauce is sometimes taken to be a tomato sauce but authentic recipes have only a very small amount of tomato, perhaps a couple of tablespoons of tomato paste.The people of Bologna traditionally serve their famous ragù with freshly made tagliatelle (tagliatelle alla bolognese). Less traditionally, the sauce is served with rigatoni or used as the stuffing for lasagne or cannelloni.The recipe issued in 1982 by the Bolognese delegation of Accademia Italiana della Cucina confines the ingredients to beef, pancetta, onions, carrots, celery, tomato paste, meat broth, white wine, and (optionally) milk or cream. However, different recipes, far from the Bolognese tradition, make use of chopped pork, chicken or goose liver along with the beef or veal for variety, or use butter with olive oil. Prosciutto, mortadella, or porcini fresh mushrooms may be added to the soffritto to enrich the sauce.
