Why it works: Syrup and sugar match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 5,842 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Lemon Ice
Ingredients
Directions
Make the syrup
Dissolve 1 pint of sugar in water to make 3 pints of thin syrup.
Combine and freeze
Combine the lemon juice with the syrup.
When the mixture begins to freeze, stir in the beaten egg whites and a little powdered sugar to make it smooth.

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 and bright lemon flavor that defines the ice.
- Sugar
- Sweetens the ice and lowers its freezing point so it stays soft and scoopable.
- Egg whites
- Whipped air and proteins stabilize the foam, giving a lighter, smoother texture.
The step that matters
Stirring in the egg whites as the mixture begins to freeze. If the mixture freezes solid before the whites are added, they cannot blend in evenly. Stirring while it is partly frozen breaks up forming ice crystals, which keeps the texture smooth rather than coarse and icy.
Swap the lemon
How well each one fits the dish's main ingredients (syrup, sugar, egg):
- Vanillafits better
- Raisinfits better
- Lemonthe original
- Figfits about as well
Fit is the average pairing score against syrup, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
