Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks add richness and the beaten whites trap air, giving the cake its light structure.
- Flour
- Sets the structure of the cake as its proteins bond and firm up during baking.
- Sugar
- Sweetens the cake and, beaten with the yolks, helps create a fine, tender crumb.
- Baking powder
- Releases gas when moistened and heated, helping the cake rise.
- Boiling water
- Adds moisture and helps the batter stay loose and tender.
The step that matters
Adding the beaten whites and boiling water just before the flour. Beaten whites hold air that gives lift, and baking powder starts releasing gas once wet. Adding the whites and water just before the flour, then baking promptly, keeps that air and gas from escaping, so the cake rises well.
