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

What each ingredient does

Ripe tomatoes
Provide the main body, moisture, and fruity flavor that the long cooking breaks down and thickens.
Sugar
Adds sweetness and, as it dissolves, draws water out of the tomatoes to help thicken the mixture.
Cider vinegar
Adds acidity that brightens the sweet tomato mixture and balances its richness.
Ground cinnamon
Adds warm aromatic spice flavor.
Whole cloves
Adds strong aromatic spice flavor that infuses the mixture as it simmers.

The step that matters

Stirring constantly during the second boil. As water evaporates, the sugar and tomato solids concentrate and thicken, and they can scorch on the bottom of the pot. Constant stirring keeps the mixture moving so it cooks evenly and does not burn.

Swap the tomato

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

  1. Mustardfits better
  2. Capsicumfits better
  3. Cucumberfits better
  4. Tomatothe original

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