Method
Make the Chocolate Base
- Set up a double boiler over gently simmering water. Combine 1/2 cup heavy cream, chopped chocolate, orange zest, and orange juice in the bowl. Stir occasionally until chocolate is completely melted and smooth, about 5-7 minutes. Remove from heat and strain through a fine mesh strainer into a large bowl to remove zest. Stir in vanilla and salt. Let cool to room temperature, about 15 minutes. The mixture should still be pourable but not warm.
Whip the Cream
- In a clean bowl, beat the remaining 1 cup heavy cream with granulated sugar using an electric mixer on medium-high speed until soft peaks form, about 2-3 minutes. The cream should hold a peak that folds over at the tip - do not overwhip or it will become grainy.
Fold and Chill
- Stir about one-third of the whipped cream into the cooled chocolate mixture to lighten it. This first addition can be more vigorous.
- Add the remaining whipped cream and fold with a rubber spatula using gentle figure-eight motions until no streaks remain. Work quickly but carefully to maintain volume.
- Divide the mousse among 6 ramekins or small glasses, filling about 3/4 full. Smooth the tops with the back of a spoon. Refrigerate uncovered for at least 2 hours, preferably 3, until fully set and firm to the touch.
Make Topping and Serve
- Just before serving, beat the 1/2 cup heavy cream with powdered sugar to soft peaks. Dollop onto each mousse and finish with a pinch of fresh orange zest. Serve cold.
Notes
For the cleanest orange flavor, use a Microplane to zest only the orange part of the peel, avoiding the bitter white pith underneath. The mousse can be made up to 2 days ahead and kept covered in the refrigerator; wait to add the whipped cream topping until just before serving. If you prefer a more intense orange flavor, add 1/4 teaspoon orange extract along with the vanilla.
