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
- Eggs
- Whites trap air and yolks add richness, giving the cake its main structure and lift.
- Flour
- Its proteins set during baking, forming the cake's crumb and holding its shape.
- Sugar
- Sweetens the cake and, boiled into syrup, helps stabilise the beaten whites.
- Baking powder
- Releases gas during baking, helping the batter rise and become light.
- Cream of tartar
- An acid that helps beaten egg whites hold their foam and stay stable.
The step that matters
Pouring the syrup over the beaten whites. The syrup must be hot enough to cook and set the whites while you keep beating, otherwise the foam can collapse or stay loose and weak. Beating until cold keeps air trapped so the cake rises.
