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

What each ingredient does

Egg whites
Whipped to stiff foam, they trap air that lifts and gives the cake its airy structure.
Egg yolks
Beaten with sugar, they add richness, colour and tender structure to the crumb.
Sugar
Sweetens the batter and helps stabilise the yolks while they are beaten.
All-purpose flour
Provides the protein and starch that set the cake's structure as it bakes.
Lemon juice
Adds acidity that brightens flavour and helps stabilise the whipped mixture.

The step that matters

Folding in the egg whites. Stiff whites hold the batter's air, so folding gently and alternating with flour keeps the bubbles intact. Stirring vigorously deflates the foam and produces a dense, flat cake.

Swap the lemon
