Triple-Chocolate Mousse Cake

I made this recipe from Cook's Illustrated for Christmas dessert. It's a good thing I got a Wii Fit for Christmas, because I feel personally responsible for making sure none of the cake goes to waste.

It's not a difficult recipe, but there are a lot of steps (most of them involve mixing heavy cream with various types of chocolate), so I'm just linking to the recipe.

This cake is both light and rich, and goes really well with coffee.
