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

What each ingredient does

Egg yolks
Emulsify and thicken the dressing as they set gently over heat.
Butter
Adds richness and body, helping the dressing feel smooth and creamy.
Cream
Adds moisture and softness, mellowing the sharpness of the vinegar.
Vinegar
Provides acidity that brightens the dressing and balances the richness.
Prepared mustard
Helps stabilize the emulsion and adds a sharp, savory note.

The step that matters

Thickening over boiling water. Egg yolks thicken when gently heated but can scramble if the heat is too high. Stir constantly over simmering, not boiling, water and stop once the mixture coats a spoon slightly, like custard.

Swap the mustard

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

  3. Asparagusfits about as well
  4. Mustardthe original

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