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 with gentle heat, giving it body and richness.
- Flour
- Stabilises the thickened mixture so it holds its body without becoming lumpy.
- Vinegar
- Provides the sharp acidity that defines the dressing's flavour.
- Mustard
- Adds sharp aroma and flavour that balances the richness of the yolks.
- Sweet cream
- Thins the cooled dressing to a pourable consistency with added richness.
The step that matters
Cook the mixture until thickened. Egg yolks thicken as their proteins set with heat, but overheating can scramble them into lumps. Cook gently in a double boiler and stop once the mixture thickens.
