Why it works: Lemon and orange match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,634 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓

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
- Lemons
- Provide the main acidity and aroma, with rinds releasing fragrant oil when rasped with sugar.
- Sugar
- Adds sweetness that balances the acidity of the citrus juice.
- Havana oranges
- Add extra juice and a milder, sweeter citrus flavour alongside the lemons.
The step that matters
Rasping the rinds with the sugar. Rubbing the rinds into the sugar breaks open the oil glands in the peel and transfers their aromatic oils into the sugar. Skipping this step leaves the lemonade tasting flatter and less fragrant.
