Why it works: Apple and quince work together. They rank in the top 1% of all ingredient pairs, and cooks put them together in 506 recipes. Both carry ethyl isobutyrate, which smells fruity, ethereal. The science ↓
Apple, Crab-apple, Peach, and Quince Jelly
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the fruit
Wash and chop the apples, crab-apples, peaches, and quinces.
Combine the chopped fruit with water in a pot and simmer until soft.
Strain the mixture through a cheesecloth to extract the juice.
Make the jelly
Measure the juice and add an equal amount of sugar.
Bring the mixture to a boil, stirring until the sugar dissolves.
Add pectin according to package instructions and boil for 1-2 minutes.
Pour the jelly into sterilized jars and seal.

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.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Provide natural pectin and acidity that help the jelly set and add fruity flavor.
- Crab-apples
- Add high natural pectin and tartness that help the jelly firm up.
- Quinces
- Contribute natural pectin and a floral aroma to the jelly.
- Sugar
- Adds sweetness and, with the fruit and pectin, helps the jelly set and keeps it preserved.
- Pectin
- Forms a gel network with sugar and acid so the juice sets into jelly.
The step that matters
Adding the pectin and boiling briefly. Pectin needs sugar and acid at a full boil to form a gel. Boiling too long or too little can leave the jelly runny or stiff, so follow the package timing closely.
Swap the peach
How well each one fits the dish's main ingredients (apple, crab, quince, sugar):
- Pearfits better
- Plumfits better
- Apricotfits about as well
- Peachthe original
Fit is the average pairing score against apple, crab, quince, sugar. Candidates are from the same food group and used in at least 100 recipes.
