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

What each ingredient does

Lettuce
Forms the bulk of the salad and provides its crisp, leafy texture.
Endive
Adds crunch and a slightly bitter note that contrasts with the dressing.
Oil
Carries flavour and coats the leaves, giving a smooth mouthfeel.
Vinegar
Adds acidity that brightens the dressing and balances the oil.

The step that matters

Remove as much water as possible. Any water left on the leaves dilutes the dressing and stops oil and vinegar from clinging, so the salad turns watery and limp. Drying the leaves thoroughly keeps the dressing concentrated on the surface and the leaves crisp.

Swap the endive

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

  1. Mustardfits better
  2. Endivethe original
  3. Cucumberfits about as well
  4. Capsicumfits about as well

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