Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Vinegar
- Supplies the sharp acidity that balances the richness of the oil.
- Oil
- Provides fat and smooth body, forming droplets suspended in the vinegar.
- Mustard
- Acts as an emulsifier, helping the oil and vinegar stay blended together.
The step that matters
Add the oil drop by drop, continuing to mix.. Oil only breaks into tiny droplets that stay suspended when it is added slowly while mixing. Adding it quickly lets the oil separate from the vinegar instead of forming a stable emulsion.
Swap the white pepper
How well each one fits the dish's main ingredients (mustard, vinegar):
- Tarragonfits better
- Capersfits better
- Dillfits better
- White pepperthe original
Fit is the average pairing score against mustard, vinegar. Candidates are from the same food group and used in at least 100 recipes.
