Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled egg yolks
- Mashed finely, they form the emulsified base that gives the dressing body.
- Thick cream
- Adds richness and moisture, giving the dressing a smooth, pourable texture.
- Melted butter
- Adds fat that enriches the dressing and helps it coat the leaves smoothly.
- Mixed mustard
- Contributes sharp flavour and helps bind the yolks and fat into an emulsion.
- Vinegar
- Adds acidity that brightens the dressing and balances the richness of the fat.
The step that matters
Carefully add vinegar until the mixture reaches a smooth, creamy consistency. Acid can cause the emulsion to thin or split if added too quickly. Adding it gradually, in small amounts, lets the yolks and fat hold together into a smooth, creamy dressing.
