Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salad oil
- Forms the body of the dressing, giving it richness and a smooth mouthfeel.
- Vinegar
- Provides acidity that brightens the dressing and balances the oil.
- Tarragon vinegar
- Adds a distinct herbal, aromatic note while contributing acidity.
The step that matters
Adding the oil slowly. Oil added too quickly does not disperse into the vinegar and will separate out instead of forming an emulsion. Adding it drop by drop while mixing lets fine droplets be suspended, so the dressing thickens and stays combined.
