What each ingredient does
- Mustard
- Adds sharp flavour and helps emulsify the oil and vinegar into a smooth sauce.
- Oil
- Provides fat, giving the sauce richness and a smooth, silky texture.
- Vinegar
- Adds acidity that brightens the sauce and balances the richness of the oil.
- Moist sugar
- Adds sweetness that balances the sharpness of the mustard and vinegar.
The step that matters
Add the oil and vinegar, stirring until smooth. Oil and vinegar naturally separate, so the sauce must be stirred thoroughly while the oil is added to form a stable, smooth emulsion rather than a greasy, split mixture.
