Prepare the meat. Cut the beef shanks into steaks, each at least 4 cm thick. Season the meat with salt, pepper, and ground nutmeg. Pour the flour into a plate. Roll the meat in flour. Fry the beef steaks in a mixture of butter and olive oil over high heat. The meat should brown. Remove the meat from the pan and cover with a lid.
Prepare the vegetables. Place the chopped vegetables in the frying pan with the fat from frying the meat. Add salt and pepper, pour in the wine, stir, and simmer for 7 minutes. Place the tomatoes in the frying pan, stir, and simmer for 5-6 minutes.
Prepare the roast. Place the beef pieces in a frying pan with the vegetables, pour in the broth, and add a sprig of rosemary. Simmer the dish for 2 hours over low heat, covering the frying pan with a lid.
