Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Quinces
Their high natural pectin helps the fruit juice thicken and set into a jelly.
Pears
Add sweet, soft fruit bulk and moisture that cooks down into the preserve.
Sugar
Sweetens the fruit and, at high concentration, helps preserve it and aids the jelly set.

The step that matters

Cook until the juice jellies.. Jelling depends on pectin, acid and sugar reaching the right concentration as water evaporates. Stopping too early leaves a runny preserve, while cooking too long can make it stiff and dark.

Swap the quince

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

  1. Vanillafits better
  2. Applefits better
  3. Plumfits better

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