Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Port wine
- Adds sweetness and depth, and its acidity helps balance the salty and savoury flavours.
- Mushroom ketchup
- Provides concentrated savoury, umami flavour that gives the sauce its body.
- Walnut pickle
- Contributes a dark, tangy, slightly bitter note that rounds out the sauce.
- Pounded anchovies
- Dissolve into the liquid to add deep salty umami without a clearly fishy taste.
- Shallots
- Release aromatic compounds slowly during steeping, adding a mild savoury onion character.
- Horseradish
- Adds pungent volatile compounds that give sharpness, which mellow during steeping.
The step that matters
Shake the bottle every day for two weeks. Daily shaking keeps the solids distributed so flavour compounds dissolve evenly into the liquid. Without it, the ingredients stay separated and the sauce tastes uneven.
