Ganache
A chocolate sauce made from a mixture of chocolate and cream, ganache may be used to fill a pastry, add a glossy glaze to a cake, or form the center of a traditional chocolate truffle. Ganache is typically created by pouring heated cream over chopped dark chocolate, then blending until smooth, although it may also be enhanced with liqueurs or extracts. Cream-to-chocolate ratios vary depending on the application; less cream results in a firmer ganache.
