Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oil
- Forms the body of the dressing and carries a smooth, rich mouthfeel.
- Malt vinegar
- Adds sharp acidity that balances the richness of the oil.
- Tarragon vinegar
- Adds a distinct herbal aroma and extra acidity.
- Egg white
- Helps emulsify the oil and vinegar, giving the dressing a smoother texture.
- Cream
- Adds body and softness, mellowing the sharpness of the vinegars.
The step that matters
Add the egg white and cream, and whisk until smooth. Oil and vinegar separate on their own. Whisking the egg white and cream in thoroughly helps form a stable emulsion, so the dressing stays smooth rather than breaking into layers.
Swap the white pepper
How well each one fits the dish's main ingredients (malt, vinegar, tarragon, egg, cream):
- Capersfits better
- Nutmegfits better
- Parsleyfits better
