From the website:
“Black Truffles (Tuber melanosporum), sometimes called black diamonds because of their excessively high price, are traditionally used as an ingredient in prepared meals and in sauces. Made with the finest authentic black truffle extract and extra virgin olive oil, this exquisite oil should only be used as a condiment, as it is too precious to use for cooking. Sprinkle a drop or two over eggs, risotto, meat or fish.”
