Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cider or wine vinegar
- Provides the sharp acidity and extracts flavour from the solids while preserving the sauce.
- Anchovies
- Adds deep savoury, umami flavour that rounds out the sauce.
- Onions
- Contribute aromatic sweetness and body as their flavour steeps into the vinegar.
- Cayenne pepper
- Supplies the sharp, lingering heat.
- Powdered cloves
- Adds warm, pungent aroma.
- Walnut catsup
- Adds dark, savoury depth and richness.
The step that matters
Standing covered for 2 days. The vinegar slowly draws flavour out of the onions, anchovies and spices over time. Keeping the jar tightly covered stops the vinegar evaporating and the aromas escaping, so the flavours blend fully before straining.
Swap the onion
How well each one fits the dish's main ingredients (pepper, clove, walnut, cider):
- Capsicumfits better
