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 of the salad.
Tomatoes: Add juiciness and acidity, and brighten the salad's flavour.
Hard boiled eggs: Add richness and protein-based texture as a topping.

Fit is the average pairing score against egg, tomato. 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).
