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

What each ingredient does

Halibut or red salmon
Forms the flaky body of the ring, set firm within the gelatin.
Gelatin
Sets the cooking liquid into a sliceable, firm jelly as it chills.
Vinegar
Adds acidity that brightens the poaching liquid and balances the fish's richness.
Onion
Contributes aromatic flavor to the poaching liquid as it simmers.

The step that matters

Boil down the remaining liquid. Gelatin only sets reliably in a well-flavored, concentrated liquid. Reducing the stock intensifies its taste and ensures enough body once chilled, so the ring holds its shape when unmolded.

Swap the onion

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

  1. Capsicumfits better
  2. Cucumberfits better
  3. Asparagusfits better
  4. Onionthe original

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