Chocolate Mousse: Mousse au Chocolat
In the top of a double boiler or in a bowl set over a pot of hot water, melt the chocolate and butter, stirring. Remove from the heat and beat with a heavy wooden spoon until smooth. Return to the heat and 1 at a time, add the yolks, beating well after the addition of each. Remove from the heat and transfer to a large bowl.
In a clean bowl, beat the egg whites until soft peaks start to form. Add 2 tablespoons of the sugar and beat until stiff.
In a third bowl, beat the cream until it becomes frothy. Add the remaining 2 tablespoons sugar and the Grand Marnier and continue beating until it holds soft peaks.
Transfer to a large decorative silver or glass bowl and refrigerate until well chilled.
To serve, spoon the reserved whipped cream on top and garnish with chocolate shavings.
Contains Raw Eggs: The Food Network Kitchen suggest caution in consuming raw and lightly cooked eggs due to the slight risk of salmonella or other food-borne illness. To reduce this risk, we recommend you use only fresh, properly refrigerated, clean grade A or AA eggs with intact shells, and avoid contact between the yolks or whites and the shell. For recipes that call for eggs that are raw or undercooked when the dish is served, use shell eggs that have been treated to destroy salmonella, by pasteurization or another approved method.
