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

What each ingredient does

Cucumber: Forms the crisp, watery bulk of the salad.
Ripe tomatoes: Add juiciness and a sweet, acidic flavour to the salad.
Olive oil: Adds fat and richness that carries flavour across the salad.
Lemon juice: Brightens the salad with acidity and balances the oil.
Shallot: Adds a sharp, aromatic onion flavour.

Fit is the average pairing score against cucumber, tomato, lemon, olive, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
