Fry pancetta until golden, set aside. Then sear the beef and pork mince is in batches until browned, set aside.
Into same pan sauté the onion, celery and carrot for 5-10 mins. Add garlic and cook for few more minutes. Add the wine and cook until mostly evaporated. Add the thyme and bay leaves, then stir in the tomato paste.
Add the meats back into the pan, top with the stock, add the milk and Parmesan rind then cover and place into 140 C oven for 3-4 hours until reduced and thickened. The flavours will be RICH and delicious. Check every 1 hour and top up with stock if needed. Goes well with fresh pasta 🔥
