Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Olive oil
Forms the body of the dressing and carries flavour, coating the leaves with richness.
Vinegar
Adds acidity that sharpens the dressing and balances the oil.
Lettuce
Provides the crisp leaves that the dressing coats and holds.

The step that matters

Dress the salad just before serving. Vinegar and salt draw water out of lettuce leaves, so dressing them early makes the greens limp and soggy. Adding dressing at the last moment keeps them crisp.

Swap the white pepper

How well each one fits the dish's main ingredients (vinegar, olive, sauce, lettuce):

  1. Capersfits better
  2. Tarragonfits better
  3. Garlicfits better
  4. White pepperthe original

Fit is the average pairing score against vinegar, olive, sauce, lettuce. Candidates are from the same food group and used in at least 100 recipes.
