Dark Chocolate Mousse with Orange Whipped Cream

Even a simple dessert can make a big statement. This rich chocolate mousse, topped with a cloud of citrusy cream, doesn't require you to make a custard or use any gelatin. Instead, it's set by folding whipped cream into an easy chocolate ganache that's been enriched with crème fraîche; the milk solids give the mixture a mousse-like texture and structure. Scoop the chocolate mousse into a shallow bowl -- its airiness allows you to pile it high without it collapsing -- then crown it with orange-scented whipped cream so that it towers even more impressively over your dinner table. Give your guests bowls and let them scoop their own portions. Serve alongside cookies or shortbread.
