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 give the sauce a deep, savoury saltiness.
- Walnut ketchup
- Adds dark, concentrated savoury flavour as the base of the sauce.
- Port wine
- Provides sweetness and body to the liquid base of the sauce.
- Lemon
- Adds acidity that brightens the rich, savoury flavours.
- Horseradish
- Contributes sharp, pungent heat that mellows during gentle boiling.
The step that matters
Boil gently until the rawness is gone. Gentle boiling cooks off the raw, harsh edge of the alcohol and aromatics and blends the flavours. Boiling too hard can evaporate too much liquid and make the sauce overly concentrated.
Swap the walnut
How well each one fits the dish's main ingredients (port wine, wine, ketchup, lemon, shallot, pepper, horseradish):
- Chestnutfits about as well
