Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushroom ketchup
- Provides deep savory, umami flavor as the sauce's main liquid base.
- Coarse sea salt
- Seasons the sauce and draws moisture from the shallot and spices during steeping.
- Black pepper
- Adds sharp, pungent heat that carries through the long steeping period.
- Port wine
- Adds sweetness and fruity depth that rounds out the sharp, savory notes.
- Chili vinegar
- Adds acidity that brightens the sauce and helps preserve it during aging.
The step that matters
Steeping in a warm place. Flavors develop slowly as the spices, shallot and salt infuse the liquid over time. Too little time or too little warmth leaves the sauce sharp and unblended, so the full 24 hours and the week of standing matter.
Swap the allspice
How well each one fits the dish's main ingredients (pepper, shallot, mushroom, ketchup, port wine, vinegar):
- Tarragonfits better
