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 and hold the dressing between their slices.
Onion
Adds sharp aroma and bite that balances the richer dressing.
Vinegar
Provides acidity that brightens the flavor and seasons the potatoes.
Salad oil or bacon fat
Adds fat that carries flavor and gives the potatoes a smooth, coated mouthfeel.

The step that matters

Mixing the potatoes gently. Pouring the salad between bowls and shaking it coats the slices evenly without mashing them. Crushed potato releases starch and turns the salad pasty, so gentle tossing keeps the slices intact and the texture pleasant.

Swap the onion

How well each one fits the dish's main ingredients (potato, vinegar, parsley, pepper):

  1. Carrotfits better
  2. Capsicumfits better
  3. Shallotfits better
  4. Onionthe original

Fit is the average pairing score against potato, vinegar, parsley, pepper. Candidates are from the same food group and used in at least 100 recipes.
