bittersweet chocolate

The classic Opera Cake is a work in six acts.

Two kinds of chocolate, dark cocoa, intense vanilla and coffee, and a crunch of almond turn a fine chocolate cake into an opulent one.

This may be my favorite frozen chocolate mousse. It is intensely fudgy, with the unexpected touches of pistachio and Marsala. I also like the hint of coffee in the chocolate sauce, and the ease of making everything ahead.
