Peposo is a traditional Tuscan beef stew that originated in Florence. It is made with beef, typically the tougher cuts like chuck or shank, which are slow-cooked in a rich sauce made with red wine, garlic, black pepper, and sometimes tomato. The long cooking time allows the meat to become tender and flavorful, and the sauce thickens to a rich and hearty consistency. Peposo is often served with crusty bread or polenta, making it a comforting and satisfying dish.
