Follow these steps to create your own Bloody Bolognese:

1. Sauté Vegetables: In a large skillet, heat olive oil over medium heat. Add the onion, garlic, carrot, and celery. Cook until softened, about 5-7 minutes.
2. Brown the Meat: Increase the heat to medium-high. Add the ground beef and Italian sausage, breaking it apart with a wooden spoon. Cook until browned, about 8-10 minutes.
3. Add Tomatoes: Stir in the tomato purée, diced tomatoes, and tomato paste. Mix well to combine.
4. Season the Sauce: Add dried oregano, dried basil, salt, and pepper. Stir to incorporate all flavors.
5. Add Broth and Wine: Pour in the beef broth and red wine (if using). Mix well and let it come to a simmer.
6. Simmer: Reduce heat to low. Cover the skillet and let the sauce simmer for at least 45 minutes. Stir occasionally to prevent sticking.
7. Finish with Milk: Stir in the whole milk about 10 minutes before serving. This enriches the sauce and gives it a creamy texture.
8. Cook Pasta: In a separate pot, cook your chosen pasta according to package instructions. Drain and reserve a little pasta water.
9. Combine Pasta and Sauce: Toss the cooked pasta in the Bloody Bolognese sauce, adding reserved pasta water if needed for consistency.
10. Serve: Plate the pasta and top with freshly grated Parmesan cheese and garnish with fresh basil or parsley.

These steps outline how to prepare an incredible Bloody Bolognese sauce that will impress everyone.
