Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolk
- Emulsifies the oil and vinegar so they stay blended as a smooth dressing.
- Oil
- Provides fat and body, giving the dressing its richness and smooth mouthfeel.
- Vinegar or lemon juice
- Adds acidity that brightens the flavour and balances the richness of the oil.
The step that matters
Adding the vinegar or lemon juice. The egg yolk must be whisked with the oil first so it can hold an emulsion. Adding the acid too early or without whisking can cause the oil to separate instead of forming a smooth, stable dressing.
