Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Capers
- Provide a sharp, briny bite that brightens the sauce.
- Vinegar
- Adds acidity that sharpens the flavour and balances the richness.
- Broth or stock
- Forms the liquid base that the sauce is built on.
- Brown thickening
- Thickens the sauce so it becomes smooth and coats the spoon.
The step that matters
Boil until thick and smooth. The thickening is starch or flour-and-butter, which must be fully cooked and dispersed to thicken evenly and lose its raw floury taste. Stirring keeps lumps from forming.
Swap the shallot
How well each one fits the dish's main ingredients (capers, pepper, vinegar, anchovy, butter):
- Shallotthe original
- Mustardfits about as well
- Chivefits less well
- Lettucefits less well
Fit is the average pairing score against capers, pepper, vinegar, anchovy, butter. Candidates are from the same food group and used in at least 100 recipes.
