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

What each ingredient does

Green sweet peppers
Provide the main crisp, fresh bulk of the salad.
Bermuda onion
Adds sharp, pungent flavor that balances the sweetness of the peppers.
French dressing
Adds moisture and acidity that season the chopped vegetables.

The step that matters

Soak the peppers in ice water. Cold water firms the cell walls of the pepper, helping it stay crisp rather than limp after chopping and dressing. Chilling also keeps the salad crisp when served.

Swap the onion

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