Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lettuce
- Forms the crisp, leafy base that the dressing coats.
- Sweet oil
- Carries the flavor of the dressing and coats the leaves to keep them from drying out.
- Vinegar
- Adds acidity that sharpens the dressing and balances the oil.
- Hard boiled egg yolk
- Mashed with oil and vinegar to help emulsify and thicken the dressing.
- Mustard
- Adds sharpness and helps bind the oil and vinegar into a smoother dressing.
The step that matters
Dress the salad only when ready to serve. Salt and acid draw water out of lettuce leaves, so dressing early makes them limp and soggy. Dressing just before serving keeps them crisp.
Swap the chervil
The recipe marks chervil as optional. How well each one fits the dish's main ingredients (lettuce, pepper, vinegar, egg, mustard, sugar, cream):
- Chervilthe original
- Tarragonfits about as well
- Capersfits less well
- Dillfits less well
Fit is the average pairing score against lettuce, pepper, vinegar, egg, mustard, sugar, cream. Candidates are from the same food group and used in at least 100 recipes.
