Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushroom or oyster ketchup
- Provides a deep, savory umami base for the sauce.
- Walnut pickle
- Adds a tangy, acidic, sharply seasoned flavor to the sauce.
- Horseradish
- Contributes a sharp, pungent heat that mellows during infusion.
- Minced shallot
- Adds a mild onion-like aroma and sharpness to the infused liquid.
The step that matters
Infuse the mixture for 10 days. Flavors from the spices and aromatics need time to extract into the liquid. Too short an infusion leaves the sauce harsh and unbalanced, while the sharp horseradish and cayenne mellow gradually as the steeping continues.
