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

What each ingredient does

Plums
Provide the main body, pulp and fruit flavour of the ketchup.
Sugar
Adds sweetness and, as it thickens during boiling, helps give the ketchup body.

The step that matters

Boil until the desired consistency. Sugar and fruit pulp thicken as water evaporates during boiling. Stopping too early leaves the ketchup thin, while boiling too long can make it stiff and sticky once cooled.

Swap the plum

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

  1. Limefits better
  2. Lemonfits better
  3. Orangefits about as well
  4. Plumthe original

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