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 ↓
Lemonade, Bottled
Ingredients
Directions
Make the syrup
Dissolve the sugar in the water and boil over low heat.
Add the acetic acid and tartaric acid.
Allow the mixture to cool, then add the essence of lemon.
Bottle and seal
Pour one-sixth of the mixture into each bottle filled with water.
Add the carbonate of soda to each bottle, cork immediately, and it will be ready for use.

Shared aroma: 2-nonenal (fatty, green).
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
- Loaf sugar
- Provides sweetness and body to the syrup.
- Acetic acid
- Adds sharpness that balances the sweetness.
- Tartaric acid
- Adds tartness and helps produce the fizz when combined with soda.
- Carbonate of soda
- Reacts with the acids to release carbon dioxide, creating effervescence.
The step that matters
Adding the carbonate of soda and corking immediately. Carbonate of soda reacts with the acids to release carbon dioxide gas. If the bottle is left open, the gas escapes and the lemonade loses its fizz, so corking right away keeps the carbonation in the liquid.
