Dan Pashman, host of The Sporkful podcast, gives us a behind-the-scenes look at the economics and shady dealings of the truffle business. For a recent episode, "A Trunk Full of Truffles," he followed a blackmarket truffle dealer who sells white truffles out of the trunk of his car to some of the finest restaurants in NYC, and is on track to do $6 million in sales this year. Pashman also spoke to a sensory scientist about why truffles captivate us, and whether their high price leads us to convince ourselves they taste better than they do.
