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 Ice
Ingredients
Directions
Prepare the base
Steep the thin rind of 3 lemons in 1 quart of water until highly flavored.
In a bowl, combine 1 pint of lemon juice, 1 quart of sugar, and the flavored water.
Partially freeze the mixture.
Finish and freeze
Beat the whites of 4 eggs to a stiff froth and fold them into the partially frozen mixture.
Continue freezing until fully set.

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
- Lemon juice
- Provides the sharp acidity that defines the flavor of the ice.
- Sugar
- Sweetens the mixture and softens the texture by lowering the freezing point.
- Lemon rind
- Steeped in water to extract aromatic oils that flavor the base.
- Egg whites
- Whipped to a stiff froth, they add airy lightness to the partially frozen mixture.
The step that matters
Folding in the beaten egg whites. Egg whites must be beaten to a stiff froth and folded gently into the partly frozen mixture. Overmixing knocks out the air, and adding them to a fully liquid base lets the foam collapse, leaving a denser ice.
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.
