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 rinds
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.
Place the sugared lemons in a bowl.
Squeeze the juice of the lemons into the bowl.
Add 1.5 pounds of fine sugar to the bowl.
Mix in the hot water and 3 quarts of boiling-hot milk.
Strain
Pour through a jelly bag until perfectly clear.

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
- Supply the juice for sourness and the rind for aromatic essential oils.
- Fine sugar
- Adds sweetness and helps draw essence from the lemon peel when rubbed on.
- Hot water
- Dissolves the sugar and extracts flavour from the lemon rinds during steeping.
The step that matters
Mix in the boiling-hot milk. Milk proteins can curdle when heated in an acidic mixture like lemon juice, so the hot milk should be added to the sweetened, strained-ready mixture with care and then filtered until clear.
Swap the lemon
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.
