Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Anchovies
- Dissolve into the liquid to add deep, savory umami flavor.
- Port wine
- Adds sweetness and body while the mixture steeps.
- Mushroom ketchup
- Contributes concentrated savory, umami depth to the sauce.
- Walnut pickle
- Adds tangy, dark, fermented-style flavor that sharpens the sauce.
- Horseradish
- Provides pungent heat that mellows during the long steeping.
The step that matters
Shaking the bottle daily for two weeks. Regular shaking keeps the solids distributed so flavors extract evenly from the anchovies, shallots and spices. Skipping it can leave the sauce unevenly flavored.
