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):
- Allspicefits better
