Traditional Bolognese in Bologna is made with the following ingredients:
extra virgin olive oil, butter, carrot, onion, 1 clove garlic, celery stalk, pancetta, veal ground, pork ground, tomato paste, tomatoes, white wine, milk, salt, black pepper and Reggiano Parmighiano Cow Aged Cheese.
*** Note: it had not been made with alot of garlic. Italian Americans have a penchant for using more garlic than in Italy in their Bolognese.
*** Due to the lack of white wine in the 1920s and fresh veal, many immigrants used red wine if they could, and the meat inside of sausages, both sweet and piquant. The milk in Bolgnese is for tenderizing the meat.
