Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Vinegar
- Supplies the sharp acidity that gives the dressing its tang.
- Olive oil
- Provides fat and body, carrying flavor and forming a temporary emulsion with the vinegar.
- Fresh onion pulp
- Adds sharp aromatic flavor to the dressing.
The step that matters
Shake until thoroughly mixed. Oil and vinegar do not mix on their own. Vigorous shaking breaks the oil into tiny droplets that stay suspended briefly, giving an even dressing. It separates again if left standing.
Swap the onion
How well each one fits the dish's main ingredients (vinegar, olive):
- Tomatofits better

Fit is the average pairing score against vinegar, olive. Candidates are from the same food group and used in at least 100 recipes.
