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

What each ingredient does

Peaches
Provide the main fruit body and natural pectin that help the preserves set and thicken.
Sugar
Sweetens the fruit and, with boiling, draws water out so the mixture thickens and keeps well.
Pineapple
Adds tart, bright flavour and acidity that balances the sweetness of the peaches and sugar.

The step that matters

Boil until thick. Preserves set when enough water evaporates and sugar and fruit pectin reach a gel. Stopping too early leaves a runny result, while boiling too long can scorch the sugar and darken the flavour.

Swap the pineapple

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

  1. Vanillafits better
  2. Apricotfits better
  3. Pearfits better
  4. Pineapplethe original

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