Veal stew, or "spezzatino" in Italian, is a typical winter dish in many Northern Italian families. Serve it with some polenta for a hearty and tasty meal.
Add onion, carrot, garlic, celery and herbs to a saucepan with the oil and pork belly fat. Place over medium heat and cook until softened, about 5 minutes.
Add the veal to the pan, bring to high heat and cook until browned on all sides, about 10 minutes.
Pour the wine and simmer to let the alcohol evaporate. Mix the tomato puree with the hot water, then stir into the pan. Cover, bring to the boil, then reduce to a simmer for 30 minutes.
Add potatoes and cook 20 minutes longer or until potatoes are tender. Season with salt, stir and serve hot.
