White truffle oil is a culinary oil infused with the flavor of white truffles, a type of fungus prized for its unique aroma and taste. Typically made from a base of olive oil or other oils, it captures the essence of truffles, allowing chefs and home cooks to enhance dishes without using fresh truffles, which can be expensive and hard to find. This oil is often used to finish dishes like pasta, risotto, and salads, adding a luxurious touch. While it provides a truffle-like flavor, it's important to note that most commercial white truffle oils do not contain actual truffles, but rather synthetic flavoring.
