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

What each ingredient does

Pumpkin
Forms the bulk of the preserve and becomes tender and translucent as it cooks in syrup.
Granulated sugar
Draws out moisture and forms a thick syrup that preserves the pumpkin and adds sweetness.
Lemon juice
Adds acidity that brightens the flavour and helps the pumpkin hold its texture.
Ground ginger
Adds warm, aromatic spice to the syrup and pumpkin.

The step that matters

Pour off the syrup after a few days. Sugar draws water out of the pumpkin over the standing period, so the syrup must be drained and reboiled to thicken to the right concentration for preserving.

Swap the pumpkin

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

  1. Orangefits better
  2. Limefits better
  3. Mangofits better
  4. Pumpkinthe 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.
