Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the starch and gluten network that gives the cake its structure.
- Butter
- Creamed with sugar to trap air and add richness and tenderness.
- Sugar
- Sweetens the cake and helps hold air when creamed with butter.
- Egg whites
- Folded in to add air and lift, giving a lighter crumb.
- Egg yolks
- Add richness, moisture and emulsifying fat to the batter.
- Sour milk
- Its acidity tenderizes the crumb and reacts with leavening to aid rising.
The step that matters
Fold in the beaten egg whites. Folding gently keeps the air whipped into the egg whites. Overmixing deflates the batter, which leads to a denser, less lifted cake.
