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 ↓
Milk Lemonade to Keep a Day or Two
Ingredients
Directions
Prepare the flavourings
Pare the lemons as thin as possible.
Put 8 of the rinds into 3 quarts of hot water and let it stand for 3 hours.
Rub fine sugar on the rinds of the remaining lemons to absorb the essence.
Make the lemonade
Place the sugared rinds in a bowl and squeeze the juice from the lemons over them.
Add 1.5 pounds of fine sugar to the bowl.
Combine the infused water with the mixture and add 3 quarts of boiling milk.
Mix well and strain through a jelly bag.
Refrigerate and use the day after making.

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 sharp acidity and the aromatic oils from the rinds and juice.
- Milk
- Its proteins curdle when they meet the acid, and straining removes them to leave a clearer drink.
- Fine sugar
- Sweetens the drink and balances the sharp acidity of the lemon juice.
The step that matters
Adding the boiling milk to the lemon mixture. The acid in the lemon juice makes the milk proteins clump into curds. Those curds carry cloudiness and fine particles with them, so the drink clears when it is strained through the jelly bag.
