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 chopped flavourings.
- Pickles
- Add tangy acidity and crunch to the sauce.
- Capers
- Add a sharp, briny bite that cuts through the richness.
- Tarragon vinegar
- Adds acidity and a gentle anise-like aroma.
The step that matters
Chopping the pickles, parsley, and capers very fine. Fine pieces distribute evenly through the mayonnaise, so each spoonful has a consistent texture and flavour rather than chunks of sharp pickle or caper.
Swap the onion

- Shallotfits better
