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 into a custard-like texture as they set with gentle heat.
- Vinegar
- Adds sharp acidity that balances the richness of the yolks and butter.
- Sugar
- Adds sweetness that rounds out the sharpness of the vinegar and mustard.
- Mustard
- Adds sharp, pungent flavour that gives the dressing its character.
- Melted butter
- Adds fat for smoothness and a rich mouthfeel.
- Whipped cream
- Adds fat and air, lightening the texture and softening the dressing.
The step that matters
Cook the mixture until it thickens like custard. Egg yolks thicken through gentle heat, but high heat can scramble them into lumps. Cook slowly and keep stirring so the mixture thickens smoothly.
