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

What each ingredient does

Gelatine
Sets the liquid into a wobbly, sliceable structure as it cools.
Milk
Forms the liquid base that carries the other ingredients and gives body.
Eggs
Yolks enrich and thicken the base; whipped whites add lightness and airy texture.
Sugar
Sweetens the cream and softens the eggy flavour.

The step that matters

Fold the whipped egg whites into the mixture. Whites hold air only when whipped stiff; folding gently keeps that air in, so the cream stays light instead of deflating into a dense, flat set.
