Ganache is a creamy chocolate mixture that is used as an icing or filling for cakes, and as a center for chocolate candies. It is sometimes compared to fudge, but is smoother and less sweet. Ganache is usually made of two ingredients—cream and chocolate (whether dark, milk, or white)—although other flavoring ingredients such as coffee or liqueurs can be added. The chocolate used will determine the texture of the ganache; the higher the proportion of cocoa butter, the firmer the ganache. A high proportion of chocolate also produces a firm ganache, while relatively more cream makes it more soft and moist. Ganache may be whipped so that it becomes light and pale, and butter may be added to make an easy butter cream.
