Why it works: Quince and apple 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 ↓
Quince Preserves
Ingredients
Directions
Prepare the quinces
Peel the quinces.
Place the peeled quinces in cold water with a little lemon juice to prevent browning.
Cut the quinces into halves or quarters as desired.
Cover the quinces with cold water.
Bring the water to a boil.
Drain the juice.
Make the syrup and cook
Add 2 parts sugar and 1 part water to the pot.

Skim off any foam.
Drop the quinces into the syrup.
Cook slowly until they are fully preserved.
Seal the preserves while hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Quinces
- Firm fruit that is cooked down into tender pieces and holds the preserve's body.
- Sugar
- Sweetens the preserve and, with heat, thickens the syrup and helps preserve the fruit.
- Lemon juice
- Acidity that slows browning of the cut quince flesh.
The step that matters
Cook slowly until fully preserved. Quince needs long, gentle cooking in syrup for its flesh to soften and turn color. Boiling hard can break the pieces apart and leave the syrup cloudy or uneven.
Swap the lemon
How well each one fits the dish's main ingredients (quince, sugar, apple):
- Pearfits better
- Plumfits better
- Apricotfits better
- Lemonthe original
Fit is the average pairing score against quince, sugar, apple. Candidates are from the same food group and used in at least 100 recipes.
