Why it works: Lemon and milk are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 19,053 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Lemonade
Ingredients
Directions
Combine the lemon rinds and loaf sugar in a bowl.
Pour the boiling water over the mixture and cover it tightly.
Let it stand until cool.
Add the juice of the lemons and the cowslip or sherbet.
Pour in the boiling skimmed milk to break it.
Strain the mixture through a jelly bag until fine.
If not acidic enough, add clear lemon juice or vinegar while straining.

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 citrus aroma, with rind oils flavouring the infusion.
- Loaf sugar
- Adds sweetness and balances the lemon's sharpness.
- Skimmed milk
- Boiling milk added to the mixture causes curds to form, which clarify the drink as they are strained out.
- Cowslip or pale sherbet
- Adds a light, pale sweet-floral flavour and body to the drink.
The step that matters
Pour in the boiling skimmed milk to break it. Hot milk coagulates proteins and separates impurities into curds, which the jelly bag then catches. Milk added too cold or too little may leave the drink cloudy, so it should be poured in while boiling and the mixture strained until fine.
Swap the lemon
The recipe marks lemon as optional. How well each one fits the dish's main ingredients (sugar, milk):
- Vanillafits better
- Figfits better
- Peachfits better
- Lemonthe original
Fit is the average pairing score against sugar, milk. Candidates are from the same food group and used in at least 100 recipes.
