1. Place the chocolate in a medium-size heat-proof bowl and set the bowl on top of a pot of boiling water. Turn the heat off. Stir until the chocolate is melted, remove from heat, stir in the liquor and the butter. Stir until the chocolate is completely mixed and smooth. Set aside to cool slightly.
2. In a bowl of your mixer, over medium speed beat the egg whites with salt until they form soft peaks, about 2 -3 minutes. While still beating, sprinkle in the sugar by the spoonful and continue beating until soft, shining peaks are formed, about another 2-3 minutes. Set aside.
3. In a clean bowl, whip the cream until it is fairly thick and holds a soft peak.
4. Using a large spatula, gently fold about 1/3 of the egg whites into the chocolate mix until slightly incorporated. Fold in the remaining whites. Now fold in the whipped cream gently folding until all the cream is blended in.
5. Spoon or pipe the mousse into serving dishes and refrigerate for at least an hour to firm up.
6. When ready to serve, sprinkle a few raspberries on top of the mousse. Dust with confectioner’s sugar and serve with meringue kiss cookies on the side.
TIPS & TRICKS
• Use a good dark 60% cacao chocolate.
• You can use Grand Marnier, triple sec, or Cointreau for the orange liquor. I prefer the Cointreau; it adds a clean, light orange flavor.
• Egg whites separate best when they are cold. They beat up best when they are room temperature. They can sit on your counter for hours.
• Take care when separating the egg whites to insure that there is no egg yolk in the whites. Egg yolks have fat, and fat will cause the whites to not whip up. Make sure your mixing bowl is really clean.
• Chocolate mousse can be made two days in advance. Just cover the dishes with plastic wrap. Remove the mousse from the fridge 30 minutes before serving to remove a little of the chill.
