Truffle oil is a culinary oil infused with the flavor of truffles, a type of fungus known for its strong aroma and taste. Typically made from a base oil like olive oil or grapeseed oil, it is often used as a finishing oil to enhance dishes such as pasta, risotto, and salads. There are two main types of truffle oil: white truffle oil and black truffle oil, each offering distinct flavors. While it adds a luxurious touch to meals, it's important to note that many commercial truffle oils use synthetic flavoring rather than real truffles, which can affect the overall quality and taste.
