White Truffle Oil

White truffle oil is a neutral oil, typically grapeseed or olive oil, flavored to taste like white truffle (Tuber magnatum). Many commercial versions achieve this with a lab-made truffle-aroma compound rather than by steeping real truffle in the oil, so quality and authenticity vary widely between brands; a genuine truffle-steeped oil is the exception rather than the rule. It is used as a finishing drizzle rather than a cooking oil, since heat dulls the aroma, and is added just before serving to pasta, risotto, eggs, potatoes, and soft cheeses. It offers an accessible, if less complex, way to bring truffle flavor to a dish without the cost of fresh truffle.
