Why it works: Apple and clove are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 2,774 recipes. Both carry ethyl octanoate, which smells fruity, wine. The science ↓
Marmalade of Apples
Ingredients
Directions
Prepare the apples
Scald the apples until they can be pulped from the core.
Make the syrup
Measure the same weight of sugar as the apples and dampen it with water.
Boil the sugar mixture, skimming off any foam, until it forms a thick syrup.
Cook and finish
Add the pulped apples to the syrup and boil over high heat for about 15 minutes.
Stir in the juice and zest of 1 lemon and add 6 whole cloves, then remove the cloves before filling your jars.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Provide the pulp and natural pectin that help the marmalade thicken as it cooks.
- Sugar
- Sweetens the marmalade and, as it boils into syrup, helps it set and keep.
- Lemon
- Adds acidity and zest aroma, and its juice helps the pectin set.
The step that matters
Boil the sugar mixture until it forms a thick syrup. Skimming foam keeps the finished marmalade clear, and the syrup must be thick enough before the apples go in so the fruit cooks in concentrated sugar and sets properly.
Swap the lemon

Fit is the average pairing score against apple, sugar, clove. Candidates are from the same food group and used in at least 100 recipes.
