Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Walnuts
- Provide the main crunchy, nutty texture of the salad.
- Olives
- Add briny, salty flavour and a firm texture that contrasts with the nuts.
- Hard-boiled eggs
- Add soft, mild richness and a creamy contrast to the nuts and olives.
- French dressing
- Adds acidity and oil that moisten the nuts and olives and carry flavour.
The step that matters
Chilling and drying the walnuts. Chilling in ice water stops the nuts from cooking further after boiling, and drying them well keeps the dressing from being diluted so the nuts stay crisp-textured.
Swap the mace
How well each one fits the dish's main ingredients (walnut, onion, egg, olive, lettuce):
- Capersfits better
- Tarragonfits better
- Parsleyfits better
- Macethe original
Fit is the average pairing score against walnut, onion, egg, olive, lettuce. Candidates are from the same food group and used in at least 100 recipes.
