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

What each ingredient does

Heavy cream
Whipped into stiff peaks, it adds air and a light, creamy body.
Egg yolks
Add richness and help thicken and bind the coffee base.
Black coffee
Provides the main coffee flavor and a slight bitterness.
Powdered sugar
Adds sweetness and dissolves easily into the cold liquid base.

The step that matters

Fold the whipped cream into the coffee mixture. Whipped cream holds air that gives the mousse its light texture. Folding gently, rather than stirring, keeps that air from deflating, so the mousse stays airy after freezing.
