A silky combination of cream and chocolate traditionally used by chocolatiers and pastry chefs for truffles, bonbons, and fillings.
Depending on the method of preparation, ganache takes one of three forms, each with significantly different properties.
The first form is a suspension, created by stirring together chocolate and hot cream. This form is often used in pastry and home applications where shelf stability is not a concern.
The second form is a chocolate-in-water emulsion, most commonly created by slowly introducing hot cream into melted chocolate under vigorous agitation. This is the most common preparation used by chocolatiers.
The third form is a bicontinuous microemulsion, created by applying shear force to a water-in-chocolate emulsion. This is the most structurally stable preparation with the longest shelf stability and softest mouthfeel.
(Note: Saglio et al provide initial evidence of the bicontinuous state; evidence for the microemulsion theory in Tango-Lowy et al., forthcoming)
In the fine chocolate industry, ganache is used as a filling in molded chocolate bonbons. It is also scooped into balls to make the classic chocolate truffle, or poured into a frame or container to create a slab, then cut into pieces that are enrobed in chocolate.
