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

What each ingredient does

Egg yolks
Thicken the dressing and bind it into a smooth, creamy sauce.
Vinegar
Adds acidity that gives the dressing its sharp, tangy flavour.
Flour
Stabilises the dressing so it thickens and holds together without splitting.
Cold boiled potatoes
Form the bulk of the salad and soak up the dressing as it is layered.
Sugar
Balances the acidity of the vinegar with a touch of sweetness.

The step that matters

Cooking the dressing. Egg yolks thicken only gently with heat. If the dressing is heated too fast or too long, the yolks can scramble and curdle, so it should be stirred steadily over low heat until smooth and thickened.

Swap the potato

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

  1. Shallotfits better
  2. Horseradishfits better
  3. Chivefits better
  4. Potatothe original

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