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

What each ingredient does

Green walnuts
Provide the bitter, tannin-rich base flavour that gives the catsup its character.
Vinegar
Acts as the preserving liquid and extracts flavour from the walnuts and aromatics over the long steep.
Coarse sea salt
Draws moisture out and helps preserve the mixture during the long standing period.
Anchovies
Add savoury depth, umami, and body to the finished liquid.
Eschalots
Contribute pungent, savoury onion flavour that mellows during steeping.

The step that matters

Boiling the strained liquid. Boiling for the full 30 minutes with the spices and anchovies extracts their flavour into the liquid and helps stabilise it for storage. Skimming removes foam and impurities that would otherwise cloud or spoil the catsup.

Swap the mace

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

  1. Allspicefits better
