sauté the vegetables
Place a large pan (preferably cast iron) with olive oil over medium heat. Add the onion, carrots, and celery. Sauté for 6 - 8 minutes, then add the garlic and ground beef. Pan-fry for 5 minutes over high heat or until the meat becomes brown and slightly cooked. Reduce the heat, add tomato paste and BAM Spices Sugo in Bolognese (if you can't get it in your country, use oregano, rosemary, and bay leaf), and continue to cook for 2 - 3 minutes, stirring occasionally.
Increase the heat and add the wine. Cook for 2 - 3 minutes for the alcohol to evaporate, then add the diced tomatoes, beef stock, and milk. Stir, cover with a lid, and cook for 45 minutes. Uncover, and continue to cook for 25 minutes. Season to taste with salt and pepper.TipFeel free to cook the covered bolognese sauce for up to two and a half hours. The longer the sauce cooks, the more flavor it develops.
Serve the bolognese sauce with cooked pasta or gnocchi, or use it in lasagna. Optionally sprinkle with freshly grated parmesan cheese before serving.
