The black truffle method is not new. However, it has only recently become popular. Before the 1970s, black truffle salts were not commonly available. The Nobel Prize-winning team of Didier Dictre and Patrick Maravel discovered the truffle. After their discovery, the process of producing truffle salts became much more efficient. This product is now used widely as a seasoning and garnish. It is best to use small amounts. Its flavor is worth the price.
