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, flavor, and natural pectin that helps the jam thicken.
Sugar
Adds sweetness and helps the jam set by binding water and working with fruit pectin.
Orange
Its grated rind adds aromatic citrus oils and a slight bitterness that balances the sweetness.
Crushed pineapple
Adds acidity and tropical flavor, and its juice adds moisture to the fruit mixture.

The step that matters

Simmer gently until done. Sugar can scorch and fruit can break down or turn bitter if boiled too hard. Gentle heat lets water evaporate slowly so the sugar and pectin set into a thick, smooth jam.

Swap the orange

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

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

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