Why it works: Sugar and lemon 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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Isinglass
- Sets the mixture into a light, firm, sliceable structure as it cools.
- Egg whites
- Whipped into a foam that gives the dessert its airy, snowy texture.
- Sugar
- Adds sweetness and helps stabilize the beaten egg white foam.
- Lemon juice
- Adds acidity that balances the sweetness and helps keep the egg white foam stable.
The step that matters
Beating the thickened mixture into the egg whites. The mixture must be thickened and cool before it is beaten in. If it is still warm or runny, it will deflate the egg white foam and the dessert will not hold its airy volume when it sets.
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.
