Why it works: Mustard and vinegar are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 14,067 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mustard
- Acts as an emulsifier, helping the oil and vinegar stay blended together.
- Vinegar
- Provides the sharp acidity that balances the richness of the oil.
- Oil
- Supplies fat that gives the sauce body and a smooth mouthfeel.
The step that matters
Very slowly add the vinegar while mixing well. Adding the vinegar slowly while whisking lets the seasonings and mustard disperse evenly through the liquid. Dumping it in at once can leave the mustard clumped and the sauce poorly combined.
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.
