Why it works: Lemon and sugar are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 53,532 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Lemon Water Ice
Ingredients
Directions
Make the syrup
Take the yellow rind from the lemons as thinly as possible and put it into an enamel pan with the sugar and water.
Cover and simmer slowly for 7 minutes.
Strain the syrup.
Let it cool, then add the lemon juice.
Finish and freeze
Beat the egg whites to a very stiff froth.
Gradually mix in the cold syrup as lightly as possible.
Freeze the mixture immediately.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Egg whites
- Whipped to a stiff froth, they add airy lightness and a smooth, fluffy texture to the frozen ice.
- Sugar
- Dissolved into the water to make a syrup that sweetens the ice and keeps it from freezing rock hard.
- Lemon juice
- Provides the sharp acidity and bright lemon flavor that defines the dish.
- Lemon rind
- Simmered in the syrup to infuse its aromatic oils and lemon flavor.
The step that matters
Gradually mix in the cold syrup as lightly as possible. Egg whites hold air only while whipped. Folding gently and gradually keeps that foam from collapsing, so the frozen ice stays light instead of dense.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, egg):
- Vanillafits better
- Raisinfits about as well
- Lemonthe original
- Datesfits less well
Fit is the average pairing score against sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
