No double boiler needed! Use it for icing or filling a cake, or to make truffles. Recipes vary slightly so I wanted to post my go-to ganache so I can find it every time. And you can easily double or triple this one. My basic ganache uses a 2:1 ratio of dark chocolate to heavy cream, 3:1 ratio of white chocolate to heavy cream, somewhere in between for milk chocolate. Those measurements don't translate perfectly in a measuring cup so the 2:1 ratio is below (most common) The better the chocolate the richer the ganache. I love mixing semi-sweet with bittersweet. At room temperature it's a perfect truffle consistency. It can be flavored with extracts or liquers. Hazelnut extract makes it so yummy! Grand Marnier would be good too, but is delicious plain.
