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

What each ingredient does

Flour
Forms the main structure of the batter once it is mixed with liquid.
Egg yolks
Add richness and help bind the batter into a smooth, cohesive paste.
Egg whites
Beaten to a stiff froth and folded in, they make the batter light and airy.
Olive oil
Adds fat that tenderizes the batter and contributes moisture.

The step that matters

Incorporate the egg whites with the batter. Beaten egg whites hold air, which lightens the batter. Folding gently keeps that air in; vigorous stirring deflates the foam and leaves a dense coating.
