Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Olive oil
Supplies the fat that carries flavor and gives the dressing its smooth body.
Vinegar
Provides the sharp acidity that balances the oil and brightens the salad.
Onion juice
Adds sharp aromatic flavor that blends into the vinegar.

The step that matters

Mix quickly with the olive oil. Oil and vinegar do not mix on their own. Quick whisking breaks the oil into tiny droplets that stay suspended briefly, so the dressing coats the leaves evenly before it separates again.

Swap the onion

How well each one fits the dish's main ingredients (olive, vinegar, pepper):

  1. Capsicumfits better
  2. Tomatofits better
  3. Mustardfits better
  4. Onionthe original

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