Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Chocolate
Provides the rich flavor and, once cooled, the body that holds the mousse together.
Egg white
Whipped foam adds air, giving the mousse its light, airy texture.
Whipped cream
Adds fat and air, making the mousse soft, smooth and creamy.

The step that matters

Gradually introduce the whipped and sugared egg white. Adding whipped egg white in stages, folding gently, keeps the air bubbles intact. Dumping it in at once or stirring hard deflates the foam and leaves the mousse dense.
