First off, in a large casserole dish, heat the olive oil and brown the meats on all sides. Transfer to a plate.
Add the onion, carrots, celery, garlic and chillies to the pot and saute for 5 minutes. Add extra oil if you need.
Add the wine, tomato cans, tomato puree and balsamic vinegar. Allow to simmer for 5 minutes.
Arrange the shanks inside the casserole dish, add the bay leaves, herbs and seasoning.
Cover and bake for 2.5 – 3 hours at 160 degrees Celsius. Have the stock on hand if the sauce thickens too quick.
After roasting time is done, the meat should fall off the bone. Shred the meat, smother in sauce and serve on cooked fettuccine with grated pecorino cheese.
