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

What each ingredient does

Apples
Provide crisp texture and natural sweetness that balance the richer dressing.
Celery
Adds crunch and a fresh, slightly savoury bite.
Walnuts
Add crunch and a toasty, nutty flavour with some fat.
Lemon juice
Adds acidity that brightens the salad and slows browning of cut apples.
Mayonnaise dressing
Adds fat and creaminess that coats the fruit, vegetables and nuts.

The step that matters

Add the lemon juice before the dressing. Cut apple surfaces oxidise and turn brown quickly. Acid from the lemon juice slows this reaction, so it should be mixed in promptly after the apples are diced.

Swap the apple

How well each one fits the dish's main ingredients (celery, walnut, lemon, lettuce):

  1. Limefits better
  2. Avocadofits better
  3. Orangefits better
  4. Applethe original

Fit is the average pairing score against celery, walnut, lemon, lettuce. Candidates are from the same food group and used in at least 100 recipes.
