Truffle: An underground, irregular shaped fungus that is very similar to a mushroom. It has a thick skin that varies in color from a creamy white to black. Found mostly in Italy and France, they grow near roots of oak and beech trees and usually located by trained pigs and dogs. They are used sparingly in cooking due to their pungent taste and high cost.
Chocolate Truffle: A chocolate confection traditionally made with melted chocolate, butter, cream, sugar and various flavorings. They are often dipped in melted chocolate or coated in cocoa powder. They are called truffles due to their resemblance to the truffle fungus.
