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 as they set during gentle cooking, giving it body and emulsifying richness.
- Vinegar
- Provides the sharp acidity that defines the dressing's flavor and helps it thicken with the yolks.
- Mustard
- Adds sharp flavor and helps stabilize the emulsion.
- Sugar
- Balances the acidity of the vinegar with sweetness.
- Cream
- Thins the thickened dressing to a pourable consistency and adds richness.
The step that matters
Cooking the yolk mixture until thick. Egg yolks thicken as their proteins set with heat, but overheating will scramble them into lumps. Cook gently over the double boiler while stirring constantly, so the mixture thickens smoothly.
Swap the mustard
How well each one fits the dish's main ingredients (egg, sugar, vinegar, cream):
- Mustardthe original
- Cucumberfits about as well
- Capsicumfits about as well

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