Gourmet oil infused with the flavor from white or black truffles (a rare fungus that grows underground) that have been soaked in olive oil. The oil, which can be very strong in aroma and flavor, requires only a few drops to enhance and add the earthy truffle flavor to foods, such as meat, fish, pasta, risotto, salads, eggs, and sauces. As a very aromatic oil, it may lose much of its aroma if stored for long periods of time.
