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

What each ingredient does

Elderberries
Provide the main fruit flavour and body of the ketchup.
Wine vinegar
Adds sharp acidity, extracts flavour from the berries and helps preserve the sauce.
Sugar
Adds sweetness that balances the sharpness of the vinegar.
Whole peppercorns
Contribute a sharp, pungent spiced aroma.
Ground ginger
Adds warm, aromatic spice notes.
Anchovy paste
Adds savoury depth, rounding out the sauce without a distinct fishy taste.

The step that matters

Boil for 30 minutes. Boiling the vinegar mixture with the spices for 30 minutes drives off some water and draws flavour out of the spices, while the vinegar's acidity helps keep the sauce stable.

Swap the mace
