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

What each ingredient does

Olive oil
Adds richness and body, carrying fat-soluble flavour and giving the dressing a smooth mouthfeel.
Vinegar
Provides acidity that brightens the flavour and balances the oil.
Onion
Contributes sharp, aromatic pungency that fades as the dressing sits.

The step that matters

Stir until well combined. Oil and vinegar do not mix on their own. Thorough stirring breaks the oil into tiny droplets dispersed in the vinegar, so the dressing looks uniform. Because the droplets gradually merge and separate again, give the dressing a fresh stir or toss just before it is used.

Swap the onion

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

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

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