"When I first smelled the unique aroma of a truffle, I felt intoxicated - as if I almost forgot every scent that I had smelled before. At that moment, I knew my life would be changed by it."

Carlos Alberto Perez is now the general manager of the Chinese branch of Sabatino, a company dedicated to truffle products.

The truffle is high in nutrition value, but it cannot be planted in large scale and can only be found and harvested in the wild, making it very expensive - "the diamond of the kitchen", as it was called by French gourmet Jean Anthelme Brillat-Savarin.
