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

What each ingredient does

Eggs
Whisked over heat, they thicken and set the mousse structure as it cools.
Sugar
Sweetens the mousse and helps stabilise the whisked egg foam.
Whipped cream
Adds fat and air, giving the mousse a light, creamy texture.
Very strong coffee
Provides the main coffee flavour and a little liquid to the mixture.

The step that matters

Whisking the eggs and sugar over boiling water. Gentle heat thickens the eggs into a stable foam without scrambling them. Keeping the water at a simmer and whisking constantly prevents the eggs from cooking into lumps, and the foam then holds the air that gives the mousse its lightness.
