Why it works: Cucumber and lettuce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,409 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Tomato and Cucumber Salad
Ingredients
Directions
Prepare
Peel the tomatoes, remove the hearts, and chill them on ice.
Pare the cucumbers, chop them finely, and mix with the tomato hearts.
Make the dressing and assemble
For French dressing, mix salt, oil, and vinegar or lemon juice in a cup.
Beat the mixture with a fork or egg beater until well combined and use immediately.
Add French dressing or mayonnaise to the mixture and fill the tomato cups.
Serve each cup on a crisp lettuce leaf.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Firm tomatoes
- Provide the main body and juicy filling for the cups.
- Cucumbers
- Add crisp texture and fresh, mild flavor to the filling.
- Oil
- Adds fat and smooth body to the French dressing.
- Vinegar or lemon juice
- Adds acidity that brightens the dressing and balances the oil.
- French dressing or mayonnaise
- Coats the vegetables, adding moisture and richness.
The step that matters
Beat the dressing until well combined. Oil and vinegar separate unless beaten vigorously, so the dressing must be emulsified and used right away to keep it evenly mixed over the vegetables.
Swap the tomato
How well each one fits the dish's main ingredients (cucumber, lettuce, vinegar):
- Mustardfits better
- Beetrootfits better
- Radishfits better
- Tomatothe original
Fit is the average pairing score against cucumber, lettuce, vinegar. Candidates are from the same food group and used in at least 100 recipes.
