Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Anchovies
- Provide a salty, savoury depth that defines the sauce's character.
- Port wine
- Adds sweetness and body to the liquid base of the sauce.
- Walnut catsup
- Contributes concentrated savoury, tangy flavour to the base.
- Walnut pickles
- Add acidity and sharp flavour that balances the richer ingredients.
- Horseradish
- Adds pungent heat and aroma that mellows during gentle boiling.
The step that matters
Boil gently until the rawness is gone. Raw shallot, alcohol and horseradish carry sharp, harsh flavours. Gentle simmering mellows these and blends the ingredients, while a hard boil can over-reduce the liquid and make the flavour bitter or sharp.
Swap the mace
How well each one fits the dish's main ingredients (port wine, walnut, lemon, shallot, pepper, horseradish, mustard):
- Capersfits better
- Tarragonfits better
