Why it works: Lemon and sugar 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 ↓

Directions
Make the lemon custard
In a bowl, beat the egg yolks, lemon juice and sugar together until well combined.

Lemon and sugar 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
- Egg yolks
- Thicken on gentle heat and add richness and a smooth, custard-like body.
- Egg whites
- Whipped to stiff peaks, they give the dessert its light, airy texture.
- White sugar
- Sweetens the dessert and helps stabilise the yolks while they are beaten.
- Lemon juice
- Adds acidity and bright flavour that balances the sweetness.
The step that matters
Cook until thickened. Egg yolks set as they warm, so heating gently in the hot water bath and stopping once thickened keeps the custard smooth. Overheating can curdle it, and under-cooking leaves it runny and unstable when the whites are folded in.
Swap the lemon
How well each one fits the dish's main ingredients (egg, sugar):
- Vanillafits better
- Raisinfits about as well
- Lemonthe original
- Datesfits less well
Fit is the average pairing score against egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
