What each ingredient does
- Oil
- Forms the body of the dressing and carries flavor, and when emulsified with vinegar it coats leaves smoothly.
- Vinegar
- Adds acidity that brightens the dressing and balances the richness of the oil.
The step that matters
Gradually add the vinegar and oil. Adding the liquids slowly while stirring lets small droplets of oil disperse in the vinegar, forming a more stable emulsion. Adding them all at once makes the dressing separate quickly.
