Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into a foam that traps air, giving the cake its light, airy structure.
- Sugar
- Sweetens the cake and helps stabilize the whipped egg white foam.
- Winter wheat flour
- Its starch and proteins set during baking, giving the cake a light but firm crumb.
- Cream of tartar
- Acidifies the egg whites, stabilizing the foam so it holds more air.
The step that matters
Fold in the flour gently. Folding keeps the air bubbles in the whipped egg whites intact. Stirring or beating vigorously deflates the foam, leaving a dense, heavy cake instead of a light one.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
