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 Jdly
Ingredients
Directions
Prepare the juice
Wipe the apples with a damp cloth, remove the stem and blossom ends, and cut them into quarters.
Place the apples in a granite or porcelain-lined preserve kettle and add 1 pint of water.
Cover and cook slowly until the apples are soft, then mash them.
Drain the mixture through a coarse sieve without squeezing to avoid cloudy jelly.
Allow the juice to drip through a double thickness of cheesecloth or a jelly bag overnight.
Make the jelly
Measure the juice, boil it for 20 minutes, then add an equal quantity of heated granulated sugar.
Boil for 5 minutes, skim off any foam, and pour into scalded glasses placed on a wet cloth.
To prevent cracking, place a silver spoon in each glass before pouring in the jelly.
Fill the glasses to the brim, as the jelly will shrink while cooling.
Set and seal
Let the glasses stand in a sunny window for 24 hours, covered to protect from dust.
Seal with melted paraffin poured directly on the jelly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fall pippin apples
- Provide the pectin and tart flavor that allow the juice to set into jelly.
- Granulated sugar
- Adds sweetness and, when boiled with the juice, helps the jelly set and keep.
The step that matters
Drain without squeezing. Pressing the pulp forces cloudy particles and fine solids through the sieve, leaving the jelly hazy instead of clear. Letting the juice drip alone keeps it bright.
Swap the clove
The recipe marks clove as optional. How well each one fits the dish's main ingredients (apple, sugar, rose, geranium):
- Cinnamonfits better
- Clovethe original
- Allspicefits less well
- Nutmegfits less well
Fit is the average pairing score against apple, sugar, rose, geranium. Candidates are from the same food group and used in at least 100 recipes.
