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
- Strawberries
- Provide the main flavour and the juice that forms the drink.
- Citric acid
- Adds sharp tartness that gives the drink its acidic character.
- White sugar
- Adds sweetness that balances the sharpness of the citric acid.
The step that matters
Bring the sweetened juice to a boil and skim the foam. Boiling dissolves the sugar fully into the juice so the drink tastes evenly sweet. Skimming removes the foam that rises from the fruit, leaving a clearer, cleaner liquid before bottling.
