Flour and egg barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Eggs
Beaten whites trap air, giving the sponge its light, airy structure.
Flour
Provides the starch and gluten framework that sets the cake's crumb.
Sugar
Sweetens the cake and helps the beaten yolks become thick and pale.
Baking powder
Releases gas in the batter, helping the layers rise as they bake.
Boiling water
Adds moisture and steam, which helps the batter expand and keeps the crumb tender.

The step that matters

Adding the beaten egg whites. Stiff beaten whites are a foam that gives the sponge its lift. Stirring them in hard or overmixing collapses the air bubbles, leaving a dense, flat cake.
