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

What each ingredient does

Egg yolks
Thicken as they warm, giving the cream its rich body and custard-like structure.
Powdered sugar
Sweetens the cream and dissolves smoothly into the yolks for a silky texture.
Lemon juice
Adds acidity that brightens the flavor and balances the sweetness of the sugar.
Egg whites
Folded in whipped, they add lightness and airiness to the finished cream.

The step that matters

Stirring over low heat. Egg yolks thicken from gentle heat but scramble if overheated. Low heat and constant stirring keep the mixture smooth, so stop as soon as it thickens.

Swap the lemon
