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
Pare the lemons as thin as possible.
Put 8 lemon rinds into 3 quarts of hot water and cover for 3-4 hours.
Make the lemonade
Rub fine sugar on the lemons to attract essence and place in a bowl.
Squeeze the juice of the lemons into the bowl with the sugar.
Add the infused water and 3 quarts of boiling hot milk to the bowl.
Mix well and strain through a jelly bag until clear.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lemons
- Provide the sour acidity and the fragrant oils in the peel that flavour the drink.
- Fine sugar
- Adds sweetness and draws aromatic oils out of the lemon peel.
The step that matters
Adding the boiling hot milk. The acid in lemon juice can curdle milk, especially when it is very hot. Combine the liquids thoughtfully and strain well so the lemonade stays smooth and clear.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, milk):
