Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pippin apples
- Provide the crisp, tart body that forms the bulk of the salad.
- Celery
- Adds crunch and a fresh, slightly savory bite that contrasts the apples.
- Mayonnaise dressing
- Supplies fat and creaminess that coats the apples and celery and carries flavor.
- Egg whites
- Whipped to stiff froth, they lighten the dressing and give it a airy texture.
The step that matters
Beating the egg whites to stiff froth. Egg whites hold air only when beaten until stiff. Underbeaten whites make the dressing runny, while folding them in gently keeps the lightness.

Fit is the average pairing score against celery, lettuce, egg. 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).
