seriously, no one knows what a truffle is? it is a mushroom that grows undergrown, it has no roots, leaves, or stems, therefore it is super hard to find, usually they use dogs that can smell them. they are really rare, thus being really expensive, and the people that find them just sell them to the highty tighty restraunts so pari hilton can drop 30,000 on a shroom, spit it out and say yucky...
