Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushroom ketchup
- Provides concentrated savory, umami depth as the sauce's main liquid base.
- Minced shallot
- Adds aromatic sharpness that mellows and flavours the liquid during the long rest.
- Black pepper
- Supplies the sharp, pungent heat that gives the sauce its character.
The step that matters
The warm rest and the week of standing. The mixture needs time to steep so the spices, shallot and vinegar flavours blend and mellow. Too little time leaves the sauce harsh and unbalanced, so keep the bottle sealed and undisturbed through the full rest.
Swap the allspice
How well each one fits the dish's main ingredients (pepper, shallot, mushroom, ketchup, port wine, vinegar):
- Tarragonfits better
- Thymefits better
- Marjoramfits about as well
