Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bordeaux vinegar
- Provides the acidic liquid base that extracts and carries the flavours of the other ingredients.
- Essence of anchovy
- Adds deep savoury, umami flavour to the sauce.
- Walnut ketchup
- Contributes dark, rich savoury depth and a fermented-style complexity.
- Soy sauce
- Adds salty, savoury umami depth that rounds out the sauce.
- Shallot
- Adds a mild allium aroma and sharpness that infuses into the vinegar during steeping.
The step that matters
Shaking twice a day during steeping. Regular shaking keeps the solids in contact with the liquid so flavour extracts evenly over the two weeks. Without it, the infusion becomes uneven and the flavour weaker and patchy.
