Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Thick cream
- Adds richness and a smooth, rich body to the mousse.
- Plain chocolate
- Provides the main flavor and, as it cools, helps the mixture thicken.
- Sugar
- Sweetens the mousse and balances the bitterness of the chocolate.
- Egg whites
- Whisked into a foam, they trap air that gives the mousse its light texture.
The step that matters
Gently fold the whisked egg whites into the cooled chocolate cream. Egg white foam holds air bubbles that make the mousse light. Stirring or mixing vigorously deflates those bubbles, leaving a dense result. Folding in gently keeps the air intact. Adding the chocolate cream while it is still hot can also melt and collapse the foam, which is why it is cooled first.
