Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Mashed into the dressing, they emulsify the fat and vinegar into a smooth, creamy binder.
- Melted butter or olive oil
- Supplies fat that gives the dressing richness and a silky, moist mouthfeel.
- Vinegar
- Adds acidity that brightens the dressing and balances the richness of the fat and yolks.
- Mixed mustard
- Contributes sharp flavour and helps hold the emulsion together.
The step that matters
Stir the dressing thoroughly. Vigorous stirring of mashed yolks with fat and vinegar builds a stable emulsion. If it is under-mixed, the fat can separate and the dressing turns greasy and loose.
Swap the celery
How well each one fits the dish's main ingredients (chicken, egg, butter, vinegar, mustard, pepper):
- Tarragonfits better
- Capersfits better
- Dillfits about as well
- Celerythe original
Fit is the average pairing score against chicken, egg, butter, vinegar, mustard, pepper. Candidates are from the same food group and used in at least 100 recipes.
