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

What each ingredient does

Oil
Provides the fat that carries flavor and gives the dressing a smooth, rich mouthfeel.
Vinegar
Supplies the acidity that gives the dressing its sharp, bright tang.

The step that matters

Whisk until well mixed. Oil and vinegar do not mix naturally and separate quickly. Whisking breaks the oil into tiny droplets that stay suspended briefly, so the dressing coats the salad evenly. Whisk again before serving, because it will separate as it stands.

Swap the onion

The recipe marks onion as optional. How well each one fits the dish's main ingredients (vinegar, pepper):

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

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