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

What each ingredient does

Egg whites
Whipped to stiffness, they give the puffs their light, airy structure.
Flour
Forms the stiff batter that holds the puffs together as they cook.
Baking powder
Releases gas during cooking, helping the batter rise and puff.
Melted butter
Adds fat and richness, softening the texture of the puffs.

The step that matters

Beat the egg whites until stiff. Under-whipped whites will not hold air, so the puffs stay dense instead of light. Stiff peaks trap air that expands in the hot soup.
