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

What each ingredient does

Celery: Adds crisp texture and a fresh, mild crunch to the salad.
Walnut halves: Add a crunchy texture and a slightly bitter, nutty flavour that balances the sweet apples.
Tart apples: Provide the main body and a bright acidity that contrasts with the rich dressing.
Mayonnaise dressing: Binds the ingredients together and adds richness and moisture.
