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

What each ingredient does

Pears
Form the bulk of the preserve, softening into a spreadable fruit mass as they cook.
Sugar
Adds sweetness and, as it concentrates through cooking, helps the preserve thicken and keep.
Ginger
Contributes warm aroma and a sharp, spicy bite that balances the sweet fruit.
Lemons
Add acidity and brightness, and the rind helps the preserve set.

The step that matters

Cook the mixture until it thickens. Sugar and fruit set only once enough water has evaporated and the sugar concentrates. Undercooked preserves stay runny and may spoil, while overcooking darkens the flavour and can make the sugar crystallise or scorch.

Swap the pear

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

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

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