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

What each ingredient does

Celery: Provides the crisp, crunchy texture that gives the salad its body.
English walnut meats: Adds crunch and a slightly bitter, nutty flavor that balances the sweet apple.
Apple: Contributes sweetness, juiciness, and a fresh crisp bite to the salad.
Mayonnaise: Binds the chopped ingredients together and adds richness and moisture.
Lemon juice: Its acidity slows browning on cut apple and adds a bright flavor.

The step that matters

Dipping the apple rings in lemon juice. Cut apple surfaces oxidize and turn brown quickly when exposed to air. Acidic lemon juice slows this enzymatic browning, so the rings should be dipped soon after slicing and before they are assembled.
