Why it works: Lemon and egg are a kitchen classic. They rank in the top 19% of all ingredient pairs, and cooks put them together in 44,316 recipes. Both carry (e,e)-2,4-decadienal, which smells fatty, deep fried. The science ↓
Lemon Water Ice
Ingredients
Directions
Prepare the juice
Rasp the peel of every fourth lemon into a basin.
Squeeze the juice of the lemons into the basin.
Make and freeze
Add water and syrup to taste, then mix well.
Strain the mixture through a fine sieve into a freezing pot.
Whip the egg whites until frothy and fold them into the mixture.
Churn the mixture in the freezing pot until it reaches a soft ice consistency.

Lemon and egg barely smell alike, yet cooks put them together in 44,316 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
- Their peel and juice supply the main aroma and sharp acidity.
- Syrup
- Adds sweetness and keeps the ice soft rather than rock-hard when frozen.
- Egg whites
- Whipped and folded in, they add an airy, lighter texture to the ice.
The step that matters
Churn to a soft ice consistency. Sugar and acid lower the freezing point, so the ice stays scoopable. Churning should stop at a soft texture; if it runs too long, the ice becomes hard and icy.
Swap the lemon
How well each one fits the dish's main ingredients (syrup, egg):
- Vanillafits better
- Lemonthe original
- Raisinfits about as well
- Raspberryfits less well
Fit is the average pairing score against syrup, egg. Candidates are from the same food group and used in at least 100 recipes.
