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

What each ingredient does

Eggs
Trap air when beaten, giving the sponge its light structure and set crumb.
Flour
Provides the starch and gluten that form the cake's structure as it bakes.
Baking powder
Releases gas in the batter, making the cake rise and become airy.
Sugar
Beaten with eggs to hold air, and adds sweetness and a tender crumb.

The step that matters

Bake promptly after the final beating. Baking powder starts releasing gas as soon as it is wet, and the heat of the oven sets the batter. Delaying the bake or overbeating the flour mixture can lose air and toughen the crumb.
