Why it works: Sugar and lemon are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 53,532 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Sets the liquid so the dessert holds a soft, wobbly shape.
- Egg whites
- Beaten whites trap air, giving the dessert a light, foamy texture.
- Sugar
- Adds sweetness and body to the liquid.
- Lemon juice
- Adds acidity for a bright, tart flavour.
- Lemon rind
- Adds fragrant citrus aroma from the oils in the peel.
The step that matters
Fold in the egg whites after slight cooling. If the mixture is still very hot, it can cook the egg whites and deflate their foam. If it has cooled too far, the gelatine may begin to set before the whites are folded in evenly.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, egg):
- Vanillafits better
- Raisinfits about as well
- Lemonthe original
- Datesfits less well
Fit is the average pairing score against sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
