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

What each ingredient does

Salmon
Forms the main body of the dish, cooked gently in simmering liquid until firm and flaky.
White vinegar
Adds a light acidity to the poaching liquid, which helps firm the fish's surface.
Coarse sea salt
Seasons the poaching liquid and the fish as it cooks.

The step that matters

Boil gently after the vinegar is added. A rolling boil can break up the fish and make the flesh dry and ragged. Keeping the liquid at a gentle simmer cooks the salmon evenly and keeps it moist and intact.

Swap the onion

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

  1. Cucumberfits better
  2. Shallotfits better
  3. Chivefits better
  4. Onionthe original

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