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

What each ingredient does

Egg yolks
Add richness and help bind the batter together.
Egg whites
Add air and lightness, helping the wafers stay crisp and delicate.
Flour
Provides the structure that holds the wafer together as it sets.
Sugar
Adds sweetness and helps the wafers brown as they cook.
Butter
Adds fat for flavor and a tender texture.

The step that matters

Remove from the iron and roll while hot. As wafers cool they become brittle and will crack instead of bending, so they must be rolled quickly while still warm and pliable.
