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

What each ingredient does

Flour
Thickens the dressing as it cooks, giving it body and a smooth, stable texture.
Egg yolks
Set during gentle cooking to thicken the dressing and add richness and emulsifying power.
Vinegar
Adds acidity that gives the dressing its sharp, tangy flavor.
Butter
Adds fat for a rich mouthfeel and smoother, silkier texture.
Sugar
Balances the sharpness of the vinegar with sweetness.

The step that matters

Cook over simmering water until thick. Egg yolks thicken through gentle heat but can curdle or scramble if overheated. Cooking over simmering water in a double boiler keeps the temperature moderate, so the dressing thickens smoothly rather than turning grainy.

Swap the mustard

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

  1. Capsicumfits about as well
  2. Shallotfits about as well
  3. Mustardthe original
  4. Chivefits about as well

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