• 1/3 cup (3 oz./90 g) tomato paste
• 1 cup (8 fl. oz./250 ml) dry red wine
• 1 cup (8 fl. oz./250 ml) milk
• 2 cans (each 28 oz./875 g) whole tomatoes, passed through a food mill

1. In a large saute pan over medium-high heat, warm 1 Tbs. of the olive oil. Add the ground beef and pork, and season with salt and pepper. Cook, stirring occasionally, until browned, about 12 minutes. Transfer to a paper towel-lined plate. Add the pancetta to the pan and cook, stirring occasionally, until crisp, about 7 minutes. Transfer to a paper towel-lined plate.
2. Reduce the heat to medium and warm the remaining 1 Tbs. olive oil. Add the onion, carrots and celery and cook, stirring occasionally, until soft and translucent, about 8 minutes. Add the garlic and cook, stirring constantly, for 1 minute. Stir in the tomato paste and cook for 2 minutes. Add the wine and simmer until almost evaporated, about 5 minutes. Add the ground meats, pancetta, milk, tomatoes, bay leaves and cheese rind. Season with salt and pepper and bring to a simmer.
3. Cover partially, reduce the heat to medium-low and cook, stirring occasionally, until the sauce thickens, 1 1/2 to 2 hours. Remove and discard the bay leaves and cheese rind.
4. Toss the pasta with about 3 cups (24 fl. oz./750 ml) of the sauce (reserve the remaining sauce for another use). Sprinkle cheese on top. Serve immediately and pass additional cheese alongside. Serves 4 to 6.
