Black truffles are a type of edible fungus that grow underground, primarily in association with the roots of certain trees like oak and hazelnut. They are highly prized for their unique aroma and flavor, making them a sought-after ingredient in gourmet cooking. Black truffles are typically harvested in the winter months using trained dogs or pigs that can detect their strong scent. These truffles are native to regions in Europe, particularly in countries like France and Italy. They are often used in dishes such as pasta, risotto, and sauces, enhancing the overall taste with their earthy and rich profile. Due to their rarity and labor-intensive harvesting process, black truffles can be quite expensive.
