Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Act as the emulsifier, holding the oil and vinegar together as a thick, stable sauce.
- Olive oil
- Supplies the fat that gives the dressing its body, richness and smooth texture.
- Vinegar
- Adds acidity and sharpness that balances the richness of the oil and yolks.
The step that matters
Adding the oil drop by drop. Oil must be added slowly while stirring so the yolk can break it into tiny droplets. Adding it too fast overwhelms the yolk, and the emulsion splits and stays runny instead of thickening.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
