Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushroom ketchup or walnut pickle
- Provides the savory, deep umami base that defines the sauce's flavor.
- Pickled shallots
- Adds a sharp, tangy acidity that brightens the rich base.
- Grated horseradish
- Contributes a pungent, sharp heat that fades somewhat during standing.
- Allspice
- Adds warm, aromatic spice notes that round out the sauce.
The step that matters
Covering and standing for 14 days. The sauce needs the full standing time so the flavors from the shallots, horseradish and spices can blend into the base. Keeping the mixture tightly covered limits contact with air, which helps preserve flavor and prevents spoilage while it steeps.
Swap the allspice
How well each one fits the dish's main ingredients (mushroom, shallot, horseradish, pepper):
- Capersfits better
- Thymefits better
- Tarragonfits better
- Allspicethe original
