Short facts : Probably the most expensive fungus

Truffle oil is a type of oil infused with the flavour and aroma of truffles, which are a type of highly prized and rare mushroom. The oil is typically made by infusing a neutral oil, such as olive or grape-seed oil, with pieces of real truffles or with synthetic truffle flavouring. Truffle oil is commonly used in cooking to add a rich, earthy flavour to dishes such as pasta, risotto, eggs and salads. It is often drizzled over finished dishes or used as a finishing touch to enhance the overall flavour profile. Truffle oil can be quite potent, so it is recommended to use it sparingly to avoid overwhelming the dish with its strong flavour.
