IllustrationWhy it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 27,039 recipes mention both. Both carry 2-nonenal, which smells fatty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sour apples
- Provide tart flavor and a crisp texture that contrasts with the dressing.
- Lemon juice
- Adds acidity that brightens the flavor and slows browning of the cut apple.
- Celery
- Adds crunch and a fresh, slightly savory flavor.
- Walnut meats
- Add crunch and a rich, nutty flavor.
- Mayonnaise dressing
- Adds moisture, richness and fat that binds the salad together.
The step that matters
Cut the apples into thin slices.. Cut apple flesh oxidizes and turns brown quickly. Lemon juice's acid slows this reaction, so the slices should be protected with it before the salad sits or is mixed.
Flavor stand-ins for the apple

- Applethe original
Fit is the average pairing score against lemon, celery, walnut, meat, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
