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

What each ingredient does

Egg yolk
Emulsifies the oil and vinegar so the dressing stays creamy instead of separating.
Salad oil
Adds richness and carries flavour in the dressing, coating the tomatoes.
Vinegar
Adds acidity that sharpens the dressing and balances the sugar.
Sugar
Softens the sharpness of the vinegar and mustard for a balanced sweetness.
Prepared mustard
Adds sharp flavour and helps stabilise the emulsified dressing.

The step that matters

Adding the vinegar slowly while whipping. Oil and vinegar are immiscible. Adding the vinegar a little at a time while whipping lets the egg yolk form a stable emulsion; pouring it in too fast can make the dressing separate and look watery.

Swap the tomato

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

  1. Horseradishfits better
  2. Capsicumfits better
  3. Shallotfits better
  4. Tomatothe original

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