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 under gentle heat, giving it body and richness.
- Vinegar
- Adds acidity that sharpens the flavour and balances the richness of the yolks and butter.
- Mustard
- Adds sharp flavour and helps emulsify the dressing, supporting a smooth texture.
- Milk
- Adds moisture and softness, loosening the custard before it thickens.
- Butter
- Adds fat for richness and a smooth, velvety mouthfeel.
- Sugar
- Adds sweetness to balance the acidity of the vinegar.
The step that matters
Cook in a double boiler until thick. Egg yolks thicken from gentle heat but can scramble if overheated. A double boiler keeps the temperature moderate, so the dressing thickens smoothly without curdling.
Swap the mustard
