While some definitely are not traditional, my “secret” ingredients for bolognese are: leeks, hot italian sausage, and merlot wine. This works with any other regular bolognese recipe, just half the amount of onions in the original recipe and add the same amount of leek. Use a ratio of 1:2 ground beef chuck to hot italian sausage, and add wine mid-way through cooking the meats to deglaze the fond with the wine and cook out the alcohol
