From Sheryl Crow: I love it when this is on the menu because it appeases any craving I might have for chocolate. And you would never have guessed that Chuck used avocado to thicken the mousse and that it would make it so delicious. Avocados are mild and sweet enough to blend seamlessly with the chocolate. This is super-healthful: no eggs, no cream, no white sugar in this mousse, and yet it's absolutely glorious.
