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

What each ingredient does

String beans
Form the main body of the salad and give a tender-crisp texture after boiling.
Onion
Adds a sharp, aromatic bite that cuts through the mild beans.
Vinegar
Adds acidity that brightens the beans and balances the flavor.

The step that matters

Boil the beans until tender, then cool them quickly. Boiling past tender leaves the beans soft and mushy. Moving them straight into cold water stops the cooking, keeping them firm and bright green.

Swap the beans

How well each one fits the dish's main ingredients (pepper, onion, vinegar):

  1. Sesamefits better
  2. Black-eyed peafits better
  3. Soybeanfits about as well
  4. Beansthe original

Fit is the average pairing score against pepper, onion, vinegar. Candidates are from the same food group and used in at least 100 recipes.
