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 ↓
Apple Marmalade
Ingredients
Directions
Prepare
Wipe the apples well, core, quarter, and slice them thinly.
Peel and add a few large apples if using very small ones to reduce excess skin.
Cook
Prepare a syrup by boiling 3 pounds of sugar in 1 pint of water for 5 minutes.
Add the sliced apples to the boiling syrup and boil rapidly for 1 hour, stirring frequently.

Apple and sugar barely smell alike, yet cooks put them together in 16,478 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
- Apples
- Provide the bulk and pectin that help the marmalade thicken as it cooks.
- Sugar
- Sweetens the marmalade and, with boiling, helps it set into a thick spread.
The step that matters
Boil rapidly and stir frequently for the full hour. Sugar and fruit only thicken when enough water evaporates and the mixture reaches a high concentration. Stirring prevents the sugar and fruit from scorching on the bottom of the pot.
Swap the clove
The recipe marks clove as optional. How well each one fits the dish's main ingredients (apple, sugar):
- Cinnamonfits better
- Gingerfits about as well
- Clovethe original
- Nutmegfits less well
Fit is the average pairing score against apple, sugar. Candidates are from the same food group and used in at least 100 recipes.
