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

What each ingredient does

Currants
Provide the main fruit body and tartness that forms the base of the ketchup.
Sugar
Adds sweetness and, as it thickens with the fruit, helps give the ketchup its body.
Vinegar
Adds acidity that balances the sweetness and helps preserve the ketchup.

The step that matters

Boil all together until quite thick. Boiling drives off water and concentrates the pectin and sugars in the fruit, so the ketchup sets to a spoonable thickness. Stopping early leaves it runny, and overcooking can scorch the sugars on the bottom of the pan.

Swap the currant

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

  1. Vanillafits better

  3. Figfits better

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