A celebrated aphrodisiac since the times of ancient Rome, the truffle emits an aroma said to be irresistible to the female persuasion — at least to female pigs. Sows are traditionally used to hunt these delicacies, because the animals go after a pheromonal compound in the truffles' scent called androstenone, which is similar to male sweat. That's why this scent also works on humans — although for some it is too strong to be appealing, while a small portion of the population can't smell androstenone at all. However, for most — male or female — the indulgence in a truffle, whether black or white, is among the most alluring culinary experiences in the world. There is no better way to sum up the sensuality of the truffle than with the words of the great gastronome Jean Anthelme Brillat-Savarin, "Truffle. As soon as the word is spoken, it awakens lustful and erotic memories among the skirt-wearing sex and erotic and lustful memories among the beard-wearing sex. This honorable parallelism comes not only from the fact that this esteemed tuber is delicious, but also because it is still believed to bring about potency, the exercise of which brings sweet pleasure."
