Prepare all the vegetables (carrot, celery, onion, and garlic) and set them aside. In a large bowl, mix the meats. Use your hands to make sure they are evenly combined.

In a deep casserole or pot over high heat, pour olive oil.

Add the chopped garlic. Stir quickly for 5 to 10 seconds or until golden, then add the onions, carrots, and celery. Add a pinch of salt into the ingredients and sauté for 2 minutes, stirring often.

Now, pour about 1 to 2 tablespoons of water into the vegetables to make them softer. Allow the vegetables to sit in the pot for a few minutes until the water is fully evaporated. If it’s taking a long time, turn up the heat. Let the water dry out completely.

Push the vegetables aside, and make some space in the pot. Add a tablespoon of olive oil into the pot. Increase the heat to high (if it’s not already on high) and add the meat into the oil a portion at a time, stirring and breaking them apart constantly. Adding the meat a portion at a time allows the liquid to evaporate and browns the meat nicely. Cook until no pink in the meat is seen. Watch over your pan and constantly stir as you do not want your meat to burn. Do this for about 5 to 8 minutes.

When you start to see the meat turning a nice brown, lower the heat to medium. Continue to stir and let it cook for a while more.

Now, it’s time to do some deglazing. Pour a cup of white wine into the pot. Using a wooden spoon, scrape all the nice brown bits stuck to the bottom of the pan. Push all the meat around with your spoon. Do this till the wine has evaporated. Lower the heat before the meat starts to stick to the pan.

Add 1 cup each of beef stock, milk, and tomato paste. Then some salt and pepper to taste. Let the sauce boil and lower to the lowest setting. Allow the sauce to simmer, half-covered, for about 4 hours. Check on the saucepan and stir occasionally.

Just 30 minutes before your meal, prepare a pot of salted boiling water and add pasta of your choice.

When the pasta is cooked, remove it from water and strain. Run it under cold water. Leave it.

The sauce should be nicely simmered by now. Adjust the seasoning before serving. Add more salt and pepper if needed. If you prefer a thicker sauce, bring the pan to high heat and boil till you achieve a thicker consistency.

Heat some oil/butter in a saucepan. Toss the cooked pasta in and spoon some sauce over. Mix gently and plate. Top with freshly grated parmigiano-reggiano.
