Boiled Sea Bass, Sauce Hollandaise

Ingredients

Directions

The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Poach the fish

  1. Fill a pot with water and add salt.

  2. Bring the water to a boil.

  3. Add the whole sea bass and cook until done, about 15‑20 minutes.

Make the hollandaise

  1. In a saucepan, melt the butter over low heat.

  2. In a bowl, whisk the egg yolks and lemon juice until thick.

  3. Slowly add the melted butter to the egg mixture, whisking constantly.

  4. Season the sauce with salt and white pepper.

Serve

  1. Serve the boiled sea bass with the hollandaise sauce drizzled on top.

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

What each ingredient does

Sea bass
Forms the main body of the dish, cooked gently in simmering water until flaky.
Egg yolks
Emulsify with melted butter to thicken the sauce into a smooth, rich hollandaise.
Butter
Provides fat that, emulsified with egg yolk, gives the sauce its creamy richness.
Lemon juice
Adds acidity that brightens the rich sauce and helps stabilise the emulsion.

The step that matters

Adding the melted butter to the yolks. Butter must be added slowly while whisking constantly so the yolk proteins can emulsify the fat. Adding it too fast, or letting the yolks overheat, can cause the sauce to split or scramble.

Swap the white pepper

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

  1. Parsleyfits better
  2. Tarragonfits better
  3. Nutmegfits better
  4. White pepperthe original

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