Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg proteins set as the mixture heats, thickening it into a smooth body.
- Butter
- Adds fat for richness and a silky mouthfeel in the dressing.
- Mustard
- Adds sharp flavor and helps hold the mixture together smoothly.
- Sugar
- Adds sweetness that balances the sharpness of the mustard and vinegar.
- Cream
- Adds richness and body, softening the dressing's texture.
- Vinegar
- Adds acidity, giving the dressing its tangy, bright flavor.
The step that matters
Cooking over boiling water until thickened. Egg proteins set gently and evenly over moderate heat, giving a smooth thickened dressing. Too much heat or too long cooking can curdle or scramble the eggs, so the mixture should be stirred and watched closely.
