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 ↓
Damson Jelly
Ingredients
Directions
Prepare the damsons
Combine 8 pounds of damsons, 8 pounds of fine sugar, and ½ pint of water in a large pot.
Boil over gentle heat for 30 minutes until the skins break.
Remove from heat and let sit for 1 hour, placing a weight on top to keep the damsons submerged in syrup.
Repeat the heating and resting process two more times.
For the final boil, cook until the mixture is a deep color where the skins are broken.
Let cool, then drain off the syrup.
Make the pectin mash
Boil a good quantity of green apples, green gooseberries, and quince cores until mashed.
Strain the mash through a sieve.
Set and pot the jelly
Combine equal parts of the strained jelly and the syrup in a pot.
Boil gently until it sets.
Pour the hot jelly into glasses or pots.

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.

Sugar and apple 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
- Damsons
- Provide the main fruit flavour and, as the skins break, the colour and body of the jelly.
- Fine sugar
- Sweetens the jelly and helps it set by binding water and preserving the fruit.
- Green apples
- Add natural pectin and acidity that help the jelly gel.
- Quince cores
- Add concentrated natural pectin to support setting.
- Green gooseberries
- Add pectin and tartness that help the jelly set.
The step that matters
Boiling until it sets. Jelly sets when enough pectin, acid and sugar are concentrated together. Boiling too briefly leaves it runny, while boiling too long can darken the flavour and make it stiff.
Swap the quince
How well each one fits the dish's main ingredients (sugar, apple):
- Pearfits better
- Vanillafits about as well
- Apricotfits about as well
- Quincethe original
Fit is the average pairing score against sugar, apple. Candidates are from the same food group and used in at least 100 recipes.
