Dark Chocolate Mousse Recipe from the Royal Orleans The Royal Orleans served this chocolate mousse. People considered it the best they had ever tasted. 12 oz Top-quality semi-sweet Chocolate (the better The chocolate, the better The mousse) 1 cup Whipping cream 1/4 cup Hot coffee 1/4 cup Hot water 3 Egg yolks, beaten 1 teaspoon Vanilla 5 Egg whites 1/3 cup Sugar Melt the chocolate in a double boiler over low heat. Watch carefully, stir during heating and remove from heat immediately when melted. I recommend using a good double boiler that is meant for melting chocolate. The Revere 2-Quart Covered Saucepan with Double Boiler Insert is a good choice. Whip the cream and set aside. Pour the hot coffee and hot water slowly into a bowl with the egg yolks, whisking briskly as you go until completely mixed. Add the vanilla to the egg yolks. Whisk in the melted chocolate. Keep whisking even after the mixture is completely combined; this will help to cool the chocolate. Whip the egg whites and the sugar until peaking but not dry Fold the egg-white meringue into the chocolate mixture carefully with a wooden spoon. Fold in the whipped cream. NOTE: The key to a great chocolate mousse is being sure the chocolate is cool to the touch before adding it to the whipped cream. Otherwise, the cream will break down. Lightly blend the two mixtures until uniform. This mousse is at its best cloudlike texture right after incorporating the whipped cream. If you want to be elegant and try something a little different, try piping it into dish-shaped champagne glasses, sprinkle chocolate shavings and powdered sugar over the top, and refrigerate. The chocolate mousse recipe sets, which gives it a different, heavier texture.
