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

What each ingredient does

Eels
Main protein; simmering slowly turns the firm flesh tender and moist.
Onion
Adds aromatic sweetness and savory depth to the cooking liquid.
Vinegar
Adds a bright acidity that balances the rich flavor of the eels.

The step that matters

Simmer until tender. Boiling vigorously toughens and breaks up delicate fish, so the liquid should be kept at a gentle simmer until the eels are tender.

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.
