Like most things in food lore, it's unclear exactly where Spaghetti with Meat Sauce was created, but one thing that is certain is that it did not originate in Italy. One theory suggests that it was created in the US about 100 years ago when there was a large influx of Italian immigrants. Between 1880 and 1924, more than four million Italians emigrated to the US, many of them from the south of Italy. This is an important clue because although Meat Sauce is often called "Bolognese" (named after a city in the north), the preparation and ingredients are actually closer to a Neapolitan ragù, which comes from the southern city of Naples (which is also where pizza was born).
