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

What each ingredient does

Bananas
Provide the main flavour and a soft, sweet body once mashed.
Egg whites
Whipped to stiff foam, they lighten the mixture and give an airy texture.
Egg yolks
Enrich the mixture and add richness and a smooth, custard-like body.
Heavy cream
Whipped to stiff peaks, it adds fat and a creamy, light texture.
Sugar
Sweetens the mixture and softens its texture as it freezes.

The step that matters

Fold in the whipped egg whites and cream gently. Whipped foams hold air that gives the parfait its lightness. Stirring or deflating them vigorously knocks out air, leaving a dense, heavy result. Fold gently with a spatula, in the order given, until just combined.

Swap the lemon
