Fish Turbot

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare the fish

  1. Boil the whitefish in salted water with the small onion for 5 minutes.

  2. Remove the skin and bones from the fish.

Make the dressing

  1. Melt the butter in a saucepan. Stir in the flour until smooth.

  2. Simmer for 3 to 4 minutes.

  3. Add the milk and grated onion, and boil until thick.

  4. Remove from heat and stir in the beaten eggs and chopped parsley.

Assemble and bake

  1. Butter a baking dish and sprinkle with powdered crackers.

  2. Layer the fish in the dish. Spread the dressing over the fish.

  3. Repeat layering until the dish is full.

  4. Top with 3 tablespoons of powdered crackers and 1 tablespoon of butter in small pieces. Pour ½ cup of milk over the top.

  5. Bake at 350°F (175°C) for 15 to 20 minutes.

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

What each ingredient does

Whitefish
Forms the flaky main body of the dish, setting firm as it bakes.
Butter
Enriches the flour roux and adds richness and flavour to the sauce.
Flour
Thickens the milk with the butter into a smooth, stable sauce.
Milk
Forms the liquid base of the sauce, which thickens as it boils.
Eggs
Set when heated, binding the dressing so it holds together when sliced.

The step that matters

Boiling the milk sauce until thick. Flour thickens only when the starch granules swell fully in boiling liquid. Stopping early leaves a thin sauce that will not bind the fish, and the eggs added afterward need the sauce hot enough to hold them together without scrambling.

Swap the onion

How well each one fits the dish's main ingredients (whitefish, butter, flour, milk, egg, parsley):

  1. Chivefits better
  2. Shallotfits better
  3. Potatofits better
  4. Onionthe original

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