White truffle is a type of fungus that grows underground, primarily in regions of Italy and France. Known for its strong aroma and unique flavor, it is often used in gourmet cooking. The most prized variety is the Tuber magnatum, which can be found in the wild during the fall and winter months. Harvesting white truffles is a delicate process, typically done with trained dogs or pigs that can detect their scent. Due to their rarity and the difficulty of cultivation, white truffles are considered a luxury ingredient, often fetching high prices in the culinary market.
