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 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 stiff foam, they lighten the frozen punch and give it a smooth, airy texture.
- Sugar
- Adds sweetness and lowers the freezing point, keeping the punch softer when frozen.
- Lemon juice
- Provides acidity that balances the sweetness and brightens the flavour.
- Kirschwasser
- Contributes cherry aroma and flavour, and a little alcohol that keeps the punch from freezing solid.
The step that matters
Add the whipped egg whites to the punch and continue freezing until done.. Egg whites must be whipped stiff and folded in while the mixture is only nearly frozen. If the base is fully solid, the whites cannot blend in and the punch loses its airy, smooth texture.
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.
