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's crumb together as it bakes.
- Egg whites
- Trap air when beaten, lightening the batter and helping the layers rise and set.
- Butter
- Adds fat for a tender crumb and rich flavour.
- Sugar
- Sweetens the cake, softens the crumb, and helps the surface brown.
- Baking powder
- Releases gas during baking, causing the batter to rise.
- Sweet milk
- Adds moisture and liquid that hydrates the flour and dissolves the sugar.
The step that matters
Fold in the egg whites. Egg whites hold air only while their foam is intact. Stirring vigorously or overmixing deflates the foam, so the layers bake up dense rather than light. Fold gently, just until no white streaks remain.
