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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg white
- Whipped into foam to give the drink a light, frothy texture.
- Sugar
- Adds sweetness and helps stabilise the foam as it is whipped.
- Lemon juice
- Adds acidity and bright lemon flavour to balance the sugar.
The step that matters
Whip until frothy. Whipping must be done before the ice and juice go in, because the egg white needs to trap air to form foam. Over-whipping or adding liquid too early can collapse the foam and leave the drink flat and thin.
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.
