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 ↓
For Lemonade
Ingredients
Directions
Make the syrup
Boil 2 cups of sugar and 1½ pints of water for 12 minutes to make syrup.
Add 1 cup of lemon juice, cool, and dilute with ice water to taste.
Make the infusion
For another method, place the lemon peel and cloves in a bottle with ½ pint of hot water.
Put the bottle in a bain‑marie or stewpan with boiling water for 1–2 hours without boiling.
Let it cool, then mix with ½ pint of fresh lemon juice, ½ pint of sugar, and a few drops of orange‑flower water.
Stir well and add 2 quarts of cold water.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Sweetens the drink and balances the sharpness of the lemon juice.
- Lemon juice
- Provides the sour, acidic flavour that defines the lemonade.
- Lemons
- Their peel supplies aromatic oils, adding fragrance and flavour during infusion.
The step that matters
Keep the infusion below boiling. Holding the bottle in water that is hot but not boiling extracts flavour from the peel gently. Boiling would draw out bitter compounds and can make the infusion taste harsh.
Swap the clove
How well each one fits the dish's main ingredients (sugar, lemon, syrup, orange):
- Cinnamonfits better
- Gingerfits better
- Peppermintfits better
- Clovethe original
Fit is the average pairing score against sugar, lemon, syrup, orange. Candidates are from the same food group and used in at least 100 recipes.
