Ingredients
For the Mousse:
- 10.5 oz (300g) orange-flavored chocolate (or 5.25 oz dark chocolate + 5.25 oz milk chocolate)
- ¾ cup (180ml) heavy whipping cream
- 1 tablespoon powdered sugar
- 2 tablespoons dark rum
- 3 large eggs, separated (yolks and whites)
- Pinch of salt
For the Orange Syrup Topping:
- 2 oranges, sliced
- Juice of 1 orange (about ¼ cup)
- 2 tablespoons granulated sugar
- ½ teaspoon vanilla sugar
Instructions
Make the Mousse Base
- Melt the chocolate: Set up a double boiler by placing a heatproof bowl over a saucepan of simmering water (don’t let the bowl touch the water). Add the chocolate and stir occasionally until completely melted and smooth. Remove from heat.
- Add flavorings: Whisk in the powdered sugar, rum, and egg yolks until well combined. The mixture should be glossy and smooth.
Whip the Cream and Egg Whites
- Whip the cream: In a clean bowl, beat the heavy cream until stiff peaks form. Set aside.
- Whip the egg whites: In another clean bowl (make sure it’s completely dry), beat the egg whites with a pinch of salt until stiff, glossy peaks form.
Fold Together
- Lighten the chocolate: Gently fold about one-third of the whipped cream into the chocolate mixture to loosen it.
- Fold in remaining cream: Add the rest of the whipped cream and fold until just combined — don’t overmix.
- Fold in egg whites: Gently fold in the whipped egg whites in two additions, using a light hand to maintain the airy texture. Stop as soon as no white streaks remain.
Chill
- Portion and chill: Divide the mousse among glasses or ramekins. Refrigerate for at least 4 hours, preferably overnight, until set.
Optional Orange Syrup Topping
- Make the syrup: In a small saucepan, combine orange juice and sugar. Heat gently over medium-low heat for about 2 minutes until slightly thickened into a light syrup. Add vanilla sugar if desired.
- Garnish: Arrange orange slices on top of set mousse and drizzle with the warm syrup.
Chef’s Tips
- Chocolate choice: For best results, use a combination of dark and milk chocolate (50/50) rather than pre-flavored orange chocolate. This gives you control over the sweetness level.
- Room temperature eggs: Separate eggs when cold, but let whites come to room temperature for maximum volume when whipping.
- Clean equipment: Ensure bowls and beaters are completely grease-free when whipping egg whites — any fat will prevent them from reaching stiff peaks.
- Make ahead: This mousse keeps beautifully in the refrigerator for up to 3 days. Add fresh garnishes just before serving.
