Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mayonnaise
- Forms the creamy base that carries the other flavours and gives the sauce its body.
- Vinegar
- Adds acidity that brightens the rich mayonnaise and balances the sweetness of the pickles.
- Cucumber pickles
- Provide crunch and a tangy, sour flavour that defines tartar sauce.
- Onion
- Adds sharp, pungent flavour and a bit of texture through its fine chopped pieces.
- Capers
- Add briny, sharp bursts of flavour that stand out against the creamy base.
The step that matters
Adding the capers just before serving. Capers release liquid and their sharp flavour can spread and dull over time. Adding them last keeps the sauce's texture firm and their briny bite distinct.
Swap the onion
How well each one fits the dish's main ingredients (vinegar, capers, cucumber):
- Mustardfits better
- Shallotfits better
- Lettucefits better
- Onionthe original
Fit is the average pairing score against vinegar, capers, cucumber. Candidates are from the same food group and used in at least 100 recipes.
