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
Prepare the lemons
Pare the lemons as thin as possible and place the rinds in hot water. Cover and let it steep for 3-4 hours.
Rub fine sugar on the lemons to attract essence, then squeeze the juice into a bowl.
Add 1.5 pounds of fine sugar to the lemon juice.
Mix and strain
Pour the hot water and boiling milk into the mixture, then mix well.
Strain through a jelly-bag until perfectly clear.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lemons
- Provide the juice and aromatic oils that give the drink its sour, fragrant flavour.
- Fine sugar
- Adds sweetness and balances the sourness of the lemon juice.
- Boiling milk
- Adds richness and softens the sharp citrus flavour.
The step that matters
Strain through a jelly-bag until perfectly clear. Straining removes fine solids and curds that cloud the drink. Letting the mixture settle and passing it slowly through a fine bag gives a clearer, smoother result.
