Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ripe tomatoes
- Provide the main body and juice of the salad, with skins removed for a softer bite.
- Cucumber
- Adds cool, crisp texture and fresh bulk to the salad.
- Cleaned lettuce leaves
- Provide a crisp, leafy base that holds the other pieces together.
- Oil
- Adds fat and smoothness, carrying flavour across the leaves and vegetables.
- Vinegar or salad dressing
- Adds acidity that brightens the salad and balances the oil.
The step that matters
Drain and dry the tomatoes after cooling. Wet tomato pieces dilute the oil and vinegar and make the salad watery, so the dressing does not cling properly. Drying them well keeps the dressing concentrated on the surfaces.
Swap the onion
How well each one fits the dish's main ingredients (tomato, cucumber, lettuce, vinegar):
- Mustardfits better
- Beetrootfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against tomato, cucumber, lettuce, vinegar. Candidates are from the same food group and used in at least 100 recipes.
