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

What each ingredient does

Barberries
Provide the main tart flavour and the ketchup's distinctive colour.
Cranberries
Add tartness and body to the fruit base.
Quince
Adds pectin, helping the ketchup thicken as it cooks.
Sugar
Balances the sharp fruit and adds sweetness.
Vinegar
Adds acidity that sharpens flavour and helps preserve the ketchup.

The step that matters

Boil the mixture for one minute. Boiling briefly after adding sugar and vinegar helps the mixture reach a stable, slightly thickened state. Boiling too long can scorch the sugar and dull the fresh fruit flavour.

Swap the onion
