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 ↓

What each ingredient does
- Lemons
- Provide the juice that gives the drink its sour, acidic flavor.
- White sugar
- Adds sweetness and body to the syrup that balances the lemon's sourness.
The step that matters
Boil for 10 minutes. Sugar must fully dissolve into the hot liquid, and boiling thickens the syrup as water evaporates. Stopping too early can leave grainy or thin syrup, while boiling too long makes it overly concentrated and sweet.
