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

What each ingredient does

Pears
Provide the bulk of the fruit and body, softening into a spreadable pulp as they cook.
Sugar
Sweetens the marmalade and draws juice out of the pears, helping it thicken as it reduces.
Lemons
Add acidity and natural pectin, which helps the marmalade set and balances the sweetness.
Whole ginger
Adds a warm, aromatic flavour to the marmalade.

The step that matters

Boil until the marmalade reaches the right thickness. Sugar and fruit set as water evaporates and pectin gels with acid and sugar. Stopping too early leaves a runny marmalade, while cooking too long can make it stiff and overly dark.

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.
