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).

  2. Sugar + appletop 18% of all pairs

    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
Main fruit; softened by simmering and set in jelly-like syrup.
Sugar
Sweetens the fruit and helps the syrup thicken and preserve it.
Apple jelly
Adds natural pectin and sweetness so the liquor sets and turns clear.

The step that matters

Simmer the quinces until soft, then drain well. Quinces are very firm and need thorough cooking before syrup can penetrate. Draining removes surface water so the syrup stays concentrated and the fruit keeps its shape.

Swap the quince

How well each one fits the dish's main ingredients (sugar, apple):

  1. Pearfits better
  2. Vanillafits about as well
  3. Apricotfits about as well
  4. 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.
