Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify the oil and vinegar, giving the dressing a thick, smooth body.
- Salad oil
- Provides the fat that forms the body of the dressing when blended into the yolks.
- Vinegar
- Adds acidity that sharpens the flavour and balances the richness of the oil and yolks.
- Cream or melted butter
- Adds richness and a silkier texture to the finished dressing.
The step that matters
Stir in the oil and vinegar drop by drop. Adding oil slowly lets the egg yolk emulsify it into the vinegar. Adding it too fast can split the dressing into separate layers of oil and liquid.
Swap the white pepper
How well each one fits the dish's main ingredients (egg, tarragon, onion, chervil, chive, cream):
