In a large pot set over medium heat, add the butter and oil and stir until melted.
Add the onion, carrots, celery, garlic, salt and sauté for roughly (5) minutes, stirring often until the vegetables are soft.
Add the ground beef and sausage in lumps and cook until all of the pink is gone. Tip: Stir and break the lumps with a wooden spoon as the meat cooks. Add the milk, tomatoes (crushed and sauce), beef broth (or bouillon cubes ground up by hand), Worcestershire Sauce, sugar and remaining seasonings.
Bring to a boil and then lower to the lowest heat setting. Simmer for (4) hours, stirring at least every thirty minutes. Taste periodically and adjust seasonings as needed
This sauce is a hybrid variation of authentic Ragu Bolognese. Serve over pasta of choice.
