Step-by-Step Directions

- Beat egg whites and kosher salt in a clean bowl until soft peaks form. Gradually add granulated sugar, continuing to beat until stiff peaks form.
- Fold a quarter of the egg whites into the chocolate mixture to lighten it, then gently fold in the remaining egg whites in two additions.
- Transfer mousse to serving dishes, cover, and chill in the fridge for at least 4 hours or overnight.
- Before serving, whip heavy cream and vanilla paste until stiff peaks form, and top the mousse with the whipped cream.
