Ragù alla bolognese
Bolognese sauce

A ragu Bolognese style is a meat sauce that is slow simmered for at least an hour to develop a complex flavor and proper thickness. Cooking the ragu in a heavy-duty enamel or similar pot will hold the heat steady and help to give a velvety texture to the ragu. Bolognese ragu is a classic sauce for lasagne and tagliatelle. The sauce also freezes beautifully.

Bolognese sauce (ragù alla bolognese in Italian) is a meat- and tomato-based pasta sauce originating in Bologna, Italy. It is typically made by simmering ground meat in tomato sauce, white wine, and stock for a long time (often upward of four hours), so that the meat softens and begins to break down into the liquid medium. The original sauce is not done with minced meat; instead, whole meat, usually beef or veal, is chopped with a knife.

Spaghetti alla Bolognese, or spaghetti bolognese which is sometimes further shortened to spag bol, is a dish invented outside of Italy consisting of spaghetti with a meat sauce. In Italy, this sauce is generally not served with spaghetti because it tends to fall off the pasta and stay on the plate. Instead, the people of Bologna traditionally serve their famous meat sauce with tagliatelle ('tagliatelle alla bolognese). Outside the traditional use, this sauce can be served with tubular pasta or represent the stuffing for lasagna or cannelloni.

True ragù alla Bolognese contains no tomato sauce — just enough fresh or canned tomato to add a hint of sweetness and another layer of flavor to a subtle, complex mix. Like all ragùs, Bolognese is characterized by its long, slow cooking, which in this case starts with simmering the meat in milk (to mellow the acidity of the raw tomatoes added later) and wine (some use white, others red), after which the tomatoes are added. The whole lot is cooked together for about two hours
