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
- Aspic jelly or consommé
- Its gelatin thickens and sets the dressing as it chills over ice.
- Salad oil
- Forms the emulsified fat base that gives the dressing its creamy body.
- Vinegar
- Adds acidity that balances the richness of the oil and jelly.
- Mustard
- Its compounds help emulsify the oil and stabilise the dressing.
- Sugar
- Rounds out the sharpness of the vinegar and mustard with mild sweetness.
The step that matters
Gradually add the oil and vinegar mixture while whisking. Adding the oil too fast or before the jelly has thickened can break the emulsion, so the dressing separates instead of turning smooth and creamy.
