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 ↓

Directions
Prepare

Stone the olives and chop them.

Serve
Just before serving, quickly mix with stiff mayonnaise and garnish with lettuce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the salad, giving it body and a soft, starchy texture.
- Eggs
- Add richness and a soft, creamy texture to the salad.
- English walnuts
- Add crunch that contrasts with the soft potatoes and eggs.
- Olives
- Add salty, briny flavor that cuts through the richness.
- Stiff mayonnaise
- Binds the salad and adds fat for a creamy, moist texture.
The step that matters
Mix gently and dress just before serving. Overmixing breaks down the soft potato and egg pieces into a mush. Adding the mayonnaise only just before serving keeps the texture intact and prevents the dressing from thinning or making the salad watery.
Swap the potato
How well each one fits the dish's main ingredients (egg, walnut, olive, lettuce):
- Beetrootfits better
- Spinachfits better
- Cucumberfits better
- Potatothe original
Fit is the average pairing score against egg, walnut, olive, lettuce. Candidates are from the same food group and used in at least 100 recipes.
