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

What each ingredient does

Currants
Provide the fruit base and natural pectin that thickens the mixture as it stews.
Sugar
Adds sweetness and, with reduction, helps thicken and preserve the cooked fruit.
Vinegar
Adds acidity that sharpens the flavour and helps keep the finished ketchup stable.

The step that matters

Stewing until quite thick. The currants and sugar must cook down far enough for the pectin and sugar to set the mixture. If it is bottled too thin, it can spoil or stay runny. Cooking it fully before adding the vinegar and spices gives a stable, spreadable result.

Swap the currant
