3 tbsp. olive oil
1 large onion, coarsely chopped
2 large carrots, peeled and coarsely chopped
3 ribs celery, coarsely chopped
4 cloves garlic, chopped
1 ½ lb. ground beef
1 ½ lb. ground pork
¼ lb. pancetta, ground or finely diced (optional)
1 cup whole milk
2 cups tomato paste
1 bottle of dry white or hearty red wine
3 bay leaves
Kosher or sea salt
Puree the chopped onion, carrots, celery, and garlic in a food processor. In a large pot, heat oil over medium-high heat. Add pureed vegetables and season generously with salt. Stirring frequently, cook vegetables until they are brown and almost all of the water has evaporated (about 20 minutes).
If using pancetta, add to vegetables and cook until brown (about 4 minutes). Add beef and pork, and season with salt. Cook until brown (about 15 to 20 minutes). Either drain mixture of fat or remove as much as you can with a spoon or ladle.
Add milk and stir until evaporated. Add tomato paste and let brown for about 3 minutes. Add wine and reduce to about half (about 5 minutes). Add water to pot until it levels just above the meat (about 2 cups). Add bay leaves. Bring to a boil then reduce heat to simmer.
Stir occasionally while seasoning with salt and pepper. As the sauce thickens, add more water (2 cups at a time). Repeat this a couple of times. Simmer for about 4 hours. Remove bay leaves before serving.
Makes about 8 servings.
