12 ounces semi sweet chocolate
1 cup heavy cream
1 stick (4 ounces) butter
Break the semi sweet chocolate in a bowl. In a saucepan, bring the cream to a boil. Pour it over the chocolate, stirring until the chocolate is melted and the mixture is smooth and well blended.
Cool mixture, then add the butter while mixture is still liquid. Allow to cool completely to set the ganache. Do not refrigerate.
