12 oz. good-quality dark chocolate, broken into pieces
4 Tablespoons unsalted butter, cut up
8 large egg whites (preferably pasteurized)
4 Tablespoons granulated sugar
1/2 cup heavy cream, whipped
Coarse sugar, optional
Place chocolate
in a medium metal bowl. Set bowl over saucepan of simmering water;
stir until melted and smooth. Stir in butter until melted. Set aside.
In another large bowl, with the mixer on high speed, beat egg whites and sugar until soft peaks form.

fold whites into chocolate mixture. Next, fold whipped cream into
whites-chocolate mixture until fully incorporated. Spoon into 8
dessert cups. Refrigerate at least two hours before serving.
Sprinkle with coarse sugar to give texture to the smooth mousse.
