Directions

Make the dressing

  2. Slowly drizzle in the oil while stirring with a wooden spoon until the mixture thickens.

  4. Taste and adjust seasoning as needed.

Cook the fish

  1. Melt butter in a sauté pan, add the fillets, season with salt, pepper, and lemon juice, and sauté on low heat until cooked.

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

What each ingredient does

Egg yolks
Emulsify the oil and vinegar, giving the dressing its thick, creamy body.
Oil
Forms the fat base of the emulsion, adding richness and smooth texture.
Vinegar
Adds acidity that brightens the dressing and balances the rich yolk and oil.
Butter
Adds fat and flavour to the pan, helping the fish brown lightly and stay moist.

The step that matters

Drizzle the oil slowly while stirring. Egg yolks can only hold oil droplets when it is added gradually. Pouring too fast breaks the emulsion, so the dressing stays thin and separates instead of thickening.

Swap the onion

How well each one fits the dish's main ingredients (egg, pepper, sugar, parsley, vinegar, lemon, butter):

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

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