  4. In a small bowl, whip the cream with an electric mixer until soft peaks form.

  5. Fold the cream into the chocolate mixture.

  6. With clean beaters, in a medium bowl, beat the egg whites with an electric mixer until stiff peaks form.

  2. Stir until the chocolate has melted and the mixture is smooth.

  3. Remove from the heat and let cool, stirring once or twice, for 30 minutes, or until thickened.

  4. In a small bowl, beat the remaining 1/2 cup of cream with an electric mixer until stiff peaks form.

  5. Fold the whipped cream into the white chocolate mixture.

  6. Spoon the mixture over the top of the chocolate mousses and refrigerate for at least 2, and up to 24, hours.
