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

What each ingredient does

Oil
Provides fat that carries flavor and gives the dressing a smooth, silky body.
Vinegar
Adds acidity for a sharp, bright taste that balances the rich oil.

The step that matters

Mix in the order given. Oil and vinegar do not stay combined on their own, so mixing them thoroughly and in sequence helps form a temporary emulsion that coats the salad more evenly.

Swap the onion

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

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

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