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

What each ingredient does

Grapes
Provide the main body, natural sweetness, and acidity that form the ketchup base.
Cinnamon
Adds warm aromatic flavor that defines the spiced character of the ketchup.
Cloves
Contribute a strong, pungent aroma typical of spiced ketchups.
Black pepper
Adds mild heat and sharp aroma that balances the grape sweetness.

The step that matters

Boil until the desired thickness. Thickening depends on evaporating water while the grape solids concentrate. Stopping too early leaves a thin sauce, while over-boiling can scorch the sugars and turn it dark and bitter.

Swap the grape

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

  1. Limefits better
  2. Orangefits better
  3. Lemonfits better
  4. Grapethe original

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