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

What each ingredient does

String beans
Form the bulk of the salad and provide its tender, crisp-cooked texture.
Oil
Adds fat and richness, carrying flavor and coating the beans smoothly.
Vinegar
Adds acidity that brightens the salad and balances the oil.
Lemon juice
Adds further acidity and fresh citrus aroma to the dressing.
Onion
Adds sharp, aromatic pungency that flavors the dressing throughout.

The step that matters

Let the beans cool before dressing. Dressing hot beans causes the oil and acid to be absorbed unevenly and can make the beans soft and greasy. Cooling first keeps their texture firm and lets the dressing coat them evenly.
