Why it works: Walnut and lettuce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 491 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓
Walnut Salad
Ingredients
Directions
Prepare the walnuts
Boil the walnuts in salted water for about 10 minutes with the sliced onion, peppercorns, bay leaf, and mace.
After boiling, plunge the walnuts into cold water and remove the skins.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Walnuts
- Provide the main body and nutty crunch of the salad.
- Celery
- Adds crisp texture and a fresh, watery crunch against the soft walnuts.
- Mayonnaise (in the method)
- Adds fat and moisture, binding the salad and coating the walnuts and celery.
The step that matters
Removing the walnut skins after boiling. Plunging the walnuts into cold water right after boiling stops the cooking and loosens the bitter papery skins, so they peel off easily. Letting them cool slowly makes the skins cling and the nuts go soft.
Swap the mace
How well each one fits the dish's main ingredients (walnut, celery, onion, lettuce):
- Tarragonfits better
- Capersfits better
- Parsleyfits better
- Macethe original
Fit is the average pairing score against walnut, celery, onion, lettuce. Candidates are from the same food group and used in at least 100 recipes.
