Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bordeaux vinegar
- Provides the sharp acidity that forms the base of the sauce and helps preserve it.
- Walnut ketchup
- Adds deep, savoury umami flavour and a rich, dark colour to the sauce.
- Essence of anchovy
- Contributes concentrated savoury depth, giving the sauce its salty, umami character.
- Indian soy
- Adds salty, fermented savouriness and further umami complexity to the blend.
- Cayenne pepper
- Supplies heat, sharpening the overall flavour of the sauce.
- Garlic
- Adds pungent aromatic flavour that mellows and infuses the sauce over the steeping period.
The step that matters
Shaking daily for two weeks. Regular shaking keeps the ingredients evenly mixed so flavours extract and blend throughout the liquid. Keeping the bottle tightly covered limits air exposure while the sauce matures.
