The flavor team

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.

  1. Quince + appletop 1% of all pairs

    Shared aroma: ethyl isobutyrate (fruity, ethereal).

    Shared aroma: beta-damascenone (apple, rose).

    Shared aroma: 1-penten-3-one (fish, pungent).

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

Quinces
Firm fruit that holds its shape through long cooking and gives the preserve its main flavour.
Sugar
Sweetens the fruit and, at high concentration, helps preserve it while forming the syrup.
Sweet apples
Add sweetness and body, and their pectin helps the preserve set.

The step that matters

Boil slowly until clear. A gentle simmer lets the syrup penetrate the fruit and keeps the pieces whole and tender. A hard, fast boil breaks the quinces apart and can make the syrup cloudy.

Swap the apple

The recipe marks apple as optional. How well each one fits the dish's main ingredients (quince, sugar):

  1. Vanillafits better
  2. Pearfits about as well
  3. Applethe original
  4. Plumfits less well

Fit is the average pairing score against quince, sugar. Candidates are from the same food group and used in at least 100 recipes.
