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):

  1. Beetrootfits better
  2. Spinachfits better
  3. Cucumberfits better
  4. 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.
