Liters of this petroleum-derived product, the colorless 2,4-dithiapentane liquid, are sourced for a few euros from Italy, Germany, or China, and then they end on your plates and refrigerators, in pasta, tartufata, oils, cheeses, and sausages, but also in expensive delicacies with a prostituted label "truffles."
If you find the smell of restaurants' truffle dishes foul, it does not mean that you do not like truffles; it could indicate that you have good taste and do not like petroleum on your plate. Unlike that intense gas-like smell, the aroma of real truffles is mild and complex.
Some will compare the difference between the natural flavor of truffles and the artificial truffle flavor with the difference between sex and sniffing dirty panties. Martha Stewart says: "Many studies have been done with truffle oil. It is fake, synthetic, and awful. Truffle oil should not be in anyone's kitchen." Bourdain was the most direct: "Let's say this once and for all. Truffle oil is not food at all."
