A rare fungus that grows underground (only several inches below ground). They come in both white and black varieties. Not all truffles are created equal, as there can be considerable quality differences between truffles due to ripeness and location of harvest. Truffles have a pungent, almost magical flavor that is greatly appreciated among gourmets.
Truffle oil
A neutral oil (or sometimes a flavorful oil like olive oil) infused with a truffle flavor. Some oils are certainly more 'truffley' than others.
