Variations of the traditional ragù sauce have evolved to include carrots, sautéed shallots, and depending on taste, either cream or milk and cheese. Typically the meats used in the sauce were diced, later to be minced or ground from meats such as beef, lamb, or pork, used individually or in combinations, such as beef and lamb. Made as either a tomato-based red sauce or a cheese-based white sauce, ragù is served as a base sauce for cooked pastas such as lasagna or ravioli in addition to many other pastas. This sauce may also be referred to as Bolognese sauce, a classic ragù sauce of Bologna, Italy.
