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 gives the salad its bulk and texture.
French dressing
Adds moisture, acidity and flavour that coats the vegetables.
Tomatoes
Contribute juiciness and a sweet-acidic flavour to the salad.
Cucumber
Adds cool, watery crunch that refreshes the salad.

The step that matters

Ensure everything is cold and the lettuce is crisp. Cold vegetables and crisp lettuce hold their structure and water content; wilted or warm leaves turn limp and soggy once dressed.

Swap the onion

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

  1. Capsicumfits better
  2. Spinachfits better
  3. Eggplantfits better
