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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Claret
- Provides the main liquid, colour and flavour of the jelly.
- Leaf gelatine
- Sets the liquid into a firm jelly as it cools.
- Egg whites and shells
- Bind and clarify the liquid, collecting cloudy particles so it runs clear.
- Loaf sugar
- Sweetens the jelly and balances the acidity of the lemon juice.
- Lemon juice
- Adds acidity and bright flavour that cuts the sweetness.
The step that matters
Strain through a scalded cloth or bag. Egg whites and shells clear the liquid only if they are given time to bind the cloudy particles. Straining through a cloth that is scalded and held in place lets the jelly run clear and without fragments.
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.
