Boiled Rock-fish

Ingredients

Directions

Prepare

  1. Clean the rockfish and place it in a fish kettle.

  2. Add enough water to cover the fish and dissolve a handful of coarse sea salt in it.

Cook

  1. Set the kettle over moderate heat and avoid boiling too fast.

  2. Skim the surface regularly.

  3. Once cooked, drain the fish and place it on a large dish.

Garnish and serve

  1. Boil the eggs hard, cut them in half, and arrange them closely on the back of the fish from head to tail.

  2. Serve with celery sauce flavored with a little cayenne pepper.

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

What each ingredient does

Rock-fish
Forms the main body of the dish, cooked gently until it flakes.
Eggs
Hard-boiled and halved, they add a firm, mild-textured garnish.

The step that matters

Keep the water at a gentle heat, not a rolling boil. Fast boiling agitates and breaks up delicate fish flesh, making it tough and ragged, while gentle heat cooks it evenly and keeps it intact.

Swap the celery

How well each one fits the dish's main ingredients (fish, egg, sauce, pepper):

  1. Capersfits better
  2. Parsleyfits better
  3. Tarragonfits better
  4. Celerythe original

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

“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
