Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the cake together as it sets.
- Egg whites
- Whipped to a foam, they trap air that lifts and lightens the crumb.
- Baking powder
- Releases gas during baking, helping the cake rise and become tender.
- Butter
- Creamed with sugar, it adds fat that gives a tender, rich texture.
- Sugar
- Creamed with butter, it sweetens the cake and helps browning.
- Sweet milk
- Adds moisture that hydrates the flour and keeps the crumb soft.
The step that matters
Folding in the whipped egg whites. Beating the whites too hard or too long makes them dry and clumpy, and overmixing deflates the air they hold. Gentle folding keeps the batter light so the cake rises evenly.
