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

What each ingredient does

Butter
Melts into the water to add richness and a tender, fat-coated texture.
All-purpose flour
Forms the batter's structure as its proteins and starches set around the air.
Egg whites
Beaten in just before use, they add air and lightness for a puffed, crisp result.

The step that matters

Folding in the beaten egg whites. Fold gently and add them just before using. Overmixing knocks out the air that gives the batter its lightness, and waiting too long lets the foam collapse.
