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 absorb the dressing's flavour.
Salad oil
Carries fat-soluble flavours and gives the dressing a smooth, rich mouthfeel.
Vinegar
Adds acidity that brightens the dressing and balances the oil and sugar.
Prepared mustard
Emulsifies the oil and vinegar so the dressing holds together rather than separating.

The step that matters

Gradually whip in the vinegar. Adding vinegar slowly, a teaspoon at a time, lets the oil and mustard emulsify into a stable dressing. Pouring it in all at once can cause the mixture to separate and become thin and greasy.

Swap the potato

How well each one fits the dish's main ingredients (sugar, mustard, pepper, celery, vinegar):

  2. Capsicumfits better
  3. Lettucefits better
  4. Potatothe original

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