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

What each ingredient does

Butter
Adds fat and richness to the batter, giving a tender texture.
Dry flour
Forms the structure of the batter as it sets during cooking.
Egg whites
Whipped in just before use to add lightness and help the batter puff.

The step that matters

Folding in the egg whites. Whipped egg whites trap air that gives lightness. Folding gently just before use keeps that air from collapsing, so the batter stays light rather than deflating into a dense coating.
