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, pectin and tartness that form the ketchup's base.
Sugar
Adds sweetness and body, and helps preserve the thick, spreadable texture.
Vinegar
Adds acidity that balances the sweetness and helps keep the ketchup stable.
Mixed red and black pepper
Adds pungent heat and aroma to the sauce.

The step that matters

Boil the mixture for 30 minutes. Boiling drives off water and lets the fruit's pectin and sugar thicken the sauce. Too short a boil leaves it thin and more prone to spoiling in the bottle.

Swap the currant

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

  1. Lemonfits better
  2. Cherryfits better
  3. Limefits better
  4. Currantthe original

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