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

What each ingredient does

Pears
Provide the fruit that softens and becomes the preserved body of the dish.
Sugar
Sweetens the dish and, in quantity, helps preserve the fruit by drawing out water.
Lemon juice
Adds acidity that brightens flavour and helps keep the pears from browning.

The step that matters

Boil until the pears are soft. Pears must be cooked fully through so they soften evenly and absorb syrup. Undercooked fruit stays firm and can leave the preserve unevenly textured.

Swap the pear

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

  1. Orangefits better
  2. Limefits better
  3. Mangofits about as well
  4. Pearthe original

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