Not true of authentic truffle oil which smells like truffles and also includes lots of truffle slices, not just one itty bitty black bit...but I agree most stuff I've seen in North America doesn't even come close to the stuff I get in Italy and Croatia.
For me, truffle oil smells like something died in a wet basement. I get an almost physical reaction of disgust. It is an odd sensation when I smell it. It is like my brain is telling me to get far away from it – fast. This doesn’t happen to me with any other food.
I feel the same way. And that is despite the fact that i first discovered and tried truffles in Italy., so got the real thing. I am the furthest from a picky eater, too, so I think it is just some inherent, unchangable dislike.
It can if it contains "truffle aroma" or "truffle essence." Look at the ingredients. Most likely, there are no real truffles but rather a chemically synthesized product engineered to smell like truffles. The real stuff is pricey, but very good.
Funny, I was just watching Jamie at Home and he finished a dish with good truffle oil, and said the cheap stuff is just chemicals made to imitate truffles. No wonder I didn't like my little bottle! Maybe I'll give it another try...
