The time I learned that truffle oil is almost never made from truffles
I've been cooking for over 20 years, mostly in Seattle restaurants, and I always thought truffle oil was just a cheap version of the real thing. Then last month, a food scientist came to our kitchen for a talk and dropped a bomb on me. He said that 99% of truffle oils on the market contain zero actual truffles. They use a synthetic chemical called 2,4-dithiapentane that mimics the smell. I felt like a fool because I had been using that stuff on fries and pastas for years thinking I was adding a touch of luxury. He showed us the ingredient list on a popular brand we had in our pantry, and sure enough, it just said "natural flavor." Now I only use real truffle shavings when I can get them, which is rare here. Has anyone else found out they were using fake ingredients without knowing it?
