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

What each ingredient does

Waxy yellow potatoes
Hold their shape when cut and absorb dressing well without turning mushy.
Vinegar
Adds acidity that brightens the flavor and balances the richness of the oil.
Olive oil
Adds fat and carries flavor, coating the potato pieces for a smooth mouthfeel.

The step that matters

Dress the potatoes while still warm. Warm potatoes are porous and absorb the vinegar, oil and seasoning far better than cold ones, so the flavor penetrates instead of sitting on the surface. Cutting and dressing them while warm gives a more evenly seasoned salad.

Swap the onion

The recipe marks onion as optional. How well each one fits the dish's main ingredients (potato, pepper, vinegar, olive, parsley, chive, celery):

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

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