Ingredients
Directions
Make the sauce
In a bowl, combine ground cloves, anchovy paste, cayenne pepper, walnut ketchup, and tomato ketchup.
Add white wine vinegar and mix well.
Cook and rest

Remove the jar and let it sit for a week.
Finish and bottle
After a week, filter the sauce and bottle it, corking tightly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Anchovy paste
- Adds deep savory saltiness that rounds out the sauce's flavour.
- Walnut ketchup
- Contributes a dark, savoury, concentrated flavour base.
- Tomato ketchup
- Adds sweetness and acidity to balance the spices.
- White wine vinegar
- Provides acidity that preserves the sauce and extracts flavours from the spices.
The step that matters
Simmering the sealed jar. Heating the jar in water gently extracts flavour without boiling the contents hard. Vigorous boiling could drive off vinegar and concentrate the sauce unevenly, so keep the water at a steady simmer and check that the jar stays covered.
Swap the walnut
How well each one fits the dish's main ingredients (clove, anchovy, pepper, ketchup, tomato, white wine, vinegar):
- Beansfits better
- Walnutthe original
- Chestnutfits about as well
- Chickpeafits about as well
Fit is the average pairing score against clove, anchovy, pepper, ketchup, tomato, white wine, vinegar. Candidates are from the same food group and used in at least 100 recipes.
