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

What each ingredient does

Tart apples: Adds crisp texture and a tangy, acidic brightness that balances the rich dressing.
Walnuts: Add crunch and a toasted, slightly bitter flavour that contrasts with the sweeter fruit.
Celery: Provides a crisp, fresh crunch and moisture to the salad.
Cream dressing: Adds moisture and richness, coating the fruit, nuts and celery so they hold together.
