Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dijon-style mustard
- Helps hold the oil and vinegar together as a stable emulsion.
- White-wine vinegar
- Adds acidity that brightens the dressing and balances the rich oil.
- Olive oil
- Provides the fat that forms the body and mouthfeel of the vinaigrette.
- Hard boiled egg
- Mashed through the sieve, it thickens the dressing and adds richness.
The step that matters
Add oil in a stream and whisk until emulsified. Adding the oil slowly while whisking breaks it into tiny droplets held in suspension by the mustard. Pouring it in too fast lets it separate back out into a greasy, unstable dressing.
Swap the parsley
How well each one fits the dish's main ingredients (mustard, wine, vinegar, olive, egg):
- Tarragonfits better
- Capersfits better
- Garlicfits better
- Parsleythe original
Fit is the average pairing score against mustard, wine, vinegar, olive, egg. Candidates are from the same food group and used in at least 100 recipes.
