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 turns tender and translucent as it absorbs the sugar syrup.
Sugar
Provides sweetness and, at high concentration, helps preserve the pumpkin and thicken the syrup.
Vinegar
Adds acidity that brightens the flavour of the sweet preserve.
Vanilla bean
Adds a warm, aromatic flavour to the syrup and fruit.

The step that matters

Continue boiling until the pumpkin is transparent and yellow. Sugar must slowly penetrate the pumpkin and concentrate the syrup. Stopping too early leaves the pieces opaque and the syrup thin. Boiling too long can break the pieces down and make the syrup overly thick or sticky.

Swap the pumpkin

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

  1. Strawberryfits better
  2. Figfits better
  3. Cherryfits better
  4. Pumpkinthe original

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