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 ↓

Ingredients
Directions
Make the jelly

Strain through a scalded bag or cloth.
Add a few drops of cochineal to enhance the color.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Eggs
- Whites and shells bind particles during heating, so the strained jelly comes out clear.
- Leaf gelatine
- Sets the liquid into a firm jelly as it cools.
- Loaf sugar
- Adds sweetness and body to the jelly.
- Lemon juice
- Adds acidity that brightens the flavour of the claret.
- Claret
- Provides the main wine flavour and the deep red colour.
The step that matters
Strain through a scalded bag or cloth. Egg whites coagulate as the mixture heats and trap impurities; straining through a clean, scalded cloth removes them, so the jelly stays clear and bright rather than cloudy.
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.
