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

What each ingredient does

Bermuda onions
Provide the main body of the salad, mellowed by soaking and pressing to reduce sharpness.
Powdered sugar
Adds sweetness that balances the sharpness of the onions and the vinegar.
Cider vinegar
Adds acidity that gives the salad its tangy flavor.

The step that matters

Drain and press the onions dry. Onions hold a lot of water and sharp sulfur compounds. Pressing them dry before dressing keeps the salad from becoming watery and dilutes the vinegar, so the seasoning clings and the flavor stays concentrated.

Swap the white pepper

How well each one fits the dish's main ingredients (onion, sugar, cider, vinegar, parsley, lettuce):

  1. Tarragonfits better
  2. Capersfits better
  3. Thymefits better
  4. White pepperthe original

Fit is the average pairing score against onion, sugar, cider, vinegar, parsley, lettuce. Candidates are from the same food group and used in at least 100 recipes.
