Why it works: Sugar and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. 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 when whipped, giving the cake its light rise, while yolks add richness and structure.
- Flour
- Sets during baking to form the cake's structure once the batter is in the oven.
- Sugar
- Sweetens the cake and helps the beaten yolks become thick and light.
- Lemon juice
- Adds acidity that helps stabilise the whipped egg whites and brightens the flavour.
The step that matters
Folding in the whites. Whipped whites hold the air that makes the sponge rise. Stirring vigorously or too long knocks that air out, so the cake bakes up dense and flat. Fold gently, just until no white streaks remain.
Swap the lemon
How well each one fits the dish's main ingredients (egg, sugar, flour):

- Lemonthe original
- Figfits about as well
Fit is the average pairing score against egg, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
