Chocolate Ganache Icing/Frosting
8 ounces of chocolate, chopped into small pieces
1 cup heavy cream
*optional 3 tbl. of flavored liqueor
Place chocolate pieces in a large bowl. Heat heavy cream on medium high until it comes to a boil. Remove from heat and immediately pour cream over chocolate and stir until completely mixed and glossy. Allow ganache to cool before pouring over cakes as a glaze. The longer you allow the ganache to cool, the thicker it will set. Typically I stick mine in the refrigerator so it is slightly cold before whipping. For piping or frosting, allow the ganache to completely cool and set up. When you are able to spoon the ganache and it can hold its texture, it is ready for piping.
As a glaze, you can easily pour ganache over cakes for a nice smooth finish. If you are looking for a chocolate whipped filling, look no further. Just whip the ganache as you would heavy cream, making sure you mixing bowl and beater are nice and cold. And whatever you do, not put your ganache in the freezer with the hopes of whipping it. It will not whip and have a curdly like texture. For a thick frosting or decorative piping, allow the ganache to cool for a truffle like texture. Anyway you decide to eat it, this ganache will satisfy your sweet tooth and chocolate cravings. Enjoy!
