Dan Pashman, host of The Sporkful podcast, gives us a behind-the-scenes look at the economics and deals of the truffle business. For a recent episode, "A Trunk Full of Truffles," he followed an independent 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.
