Why it works: Vinegar and mustard 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
- Egg yolks
- Lecithin in the yolks helps hold the oil and vinegar together as a stable emulsion.
- Oil
- Supplies the fat that gives the dressing its body and smooth, rich mouthfeel.
- Vinegar
- Provides the acidity that gives the dressing its sharp, tangy flavour.
- Mustard
- Its natural emulsifiers help keep the oil dispersed and the dressing from separating.
- Sugar
- Adds sweetness that balances the sharpness of the vinegar.
The step that matters
Slowly beat in the oil. Adding the oil gradually lets the beaten yolks break it into tiny droplets that stay suspended. If the oil goes in too fast, the emulsion can break and the dressing will separate.
Swap the mustard
How well each one fits the dish's main ingredients (vinegar, egg, sugar):
- Mustardthe original
- Capsicumfits about as well
- Cucumberfits about as well
- Shallotfits less well
Fit is the average pairing score against vinegar, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
