Both black and white truffle oils are usually made by infusing olive oil with synthetic flavoring and aroma to give it its unique truffle smell and taste. Both white and black truffles have an earthy, musty, and pungent smell and taste. However, white truffles are known to be lighter and softer in taste. Black truffles have a more potent taste and smell, with subtle nodes that remind someone of meat, fish, or broth. Despite the differences in taste and smell, white and black truffle oil both work well over pasta, pizza, potatoes, fries, meats, fish, and soups.
