Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled egg yolks
- Mash into the dressing to add richness and a creamy, emulsified body.
- Salad oil
- Provides fat that coats the leaves and carries the flavour of the herbs.
- Tarragon vinegar
- Adds acidity that brightens the dressing and balances the richness of the oil and yolks.
- French mustard
- Acts as an emulsifier that helps the oil and vinegar bind into a smooth dressing.
The step that matters
Mix until smooth before adding the lettuce. Whisking the yolks with the oil and vinegar gradually builds a stable emulsion. If the oil is added too fast or the mixture is not blended well, it splits and the dressing turns greasy and uneven on the leaves.
Swap the cabbage
