Bruise the walnuts in a large marble mortar until broken.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green walnuts
- Provide the main flavour base and dark colour as they steep in the vinegar.
- Vinegar
- Acts as the solvent and preservative, extracting flavour from the walnuts and eschalots.
- Anchovies
- Add savoury depth, a salty umami note that rounds out the sauce.
- Garlic
- Adds pungent aroma that mellows during the long steeping period.
- Coarse sea salt
- Draws moisture out and helps preserve the mixture during the long steep.
The step that matters
Stirring during the 10-day steep. Regular stirring keeps the solids in contact with the vinegar and distributes salt and flavour evenly, so extraction is uniform rather than uneven or stalled at the surface.
Swap the mace
How well each one fits the dish's main ingredients (walnut, garlic, vinegar, pepper, clove):
- Allspicefits better
- Tarragonfits better
- Thymefits better
- Macethe original
Fit is the average pairing score against walnut, garlic, vinegar, pepper, clove. Candidates are from the same food group and used in at least 100 recipes.
