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 ↓
Canning Apples and Quinces
Ingredients
Directions
Prepare the fruit
Pare and cut equal quantities of apples and quinces.
Cook the fruit
Cook the quinces in enough water to cover them until tender.
Remove the quinces and cook the apples in the same water.
Pack and seal
In a jar or kettle, layer quinces and apples until all are used.
Pour a syrup made of ½ pound sugar dissolved in a little water over the fruit.
Let it stand overnight.
The next day, heat thoroughly and seal in cans.

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.

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
- Quinces
- Firm, tart fruit that holds its shape and adds a distinctive aroma when cooked.
- Apples
- Softer fruit that cooks down and adds bulk and mild sweetness to the pack.
- Sugar
- Dissolved into syrup, it sweetens the fruit and helps preserve it.
The step that matters
Cook the quinces until tender before adding the apples. Quinces are much firmer and take longer to soften than apples. Cooking them first lets both fruits reach a similar tenderness, so the apples do not turn to mush while the quinces are still hard.
Swap the quince
How well each one fits the dish's main ingredients (apple, sugar):
- Pearfits better
- Vanillafits about as well
- Apricotfits about as well
- Quincethe original
Fit is the average pairing score against apple, sugar. Candidates are from the same food group and used in at least 100 recipes.
