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

What each ingredient does

Pears
Provide the main fruit body and pectin-bearing flesh that gives the jam its bulk and texture.
Sugar
Sweetens the jam and helps it set and keep by binding water and preserving the fruit.
Lemon juice
Adds acidity that brightens flavour and supports setting.
Lemon rind
Adds aromatic oils and a bright citrus flavour, plus some natural pectin.
Root ginger
Adds warm, pungent aroma that complements the pears and lemon.

The step that matters

Boil the pears until tender. Cook the pears just until tender, since overcooking breaks down the fruit and dulls its flavour, while undercooking leaves it firm and the jam less cohesive.

Swap the clove

The recipe marks clove as optional. How well each one fits the dish's main ingredients (pear, lemon, ginger, sugar):

  1. Cinnamonfits better
  2. Cardamomfits better
  3. Allspicefits about as well
  4. Clovethe original

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