Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the fish
Boil the fish and remove all bones.
Season the fish with white pepper and salt.
Make the sauce
In a pot, mix flour with milk until smooth.
Add onions, parsley, thyme, salt, and white pepper.
Cook over medium heat, stirring constantly until thickened.
Remove from heat.
Stir in butter and egg yolks until well combined.
Pass the mixture through a sieve.
Bake and serve
In a baking dish, layer the sauce and fish alternately, finishing with sauce on top.
Sprinkle with bread crumbs and cheese.
Bake at 350°F (175°C) for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the flaky body of the dish, set firm by baking within the sauce.
- Flour
- Thickens the milk into a smooth sauce as its starch swells when heated.
- Milk
- Forms the liquid base of the sauce, giving it a creamy, tender body.
- Butter
- Adds richness and a silky mouthfeel to the finished sauce.
- Egg yolks
- Enrich and further thicken the sauce as they set gently with heat.
- Bread crumbs
- Form a crisp, golden topping as they brown in the oven.
The step that matters
Cooking the sauce until thickened. Flour must be stirred constantly over medium heat so its starch swells evenly without lumps or scorching. Egg yolks should be added off the heat, since high heat can curdle them and make the sauce grainy.
Swap the white pepper
How well each one fits the dish's main ingredients (fish, flour, milk, onion, parsley, thyme, butter):
- Marjoramfits better
- Capersfits better
- Tarragonfits better
- White pepperthe original
Fit is the average pairing score against fish, flour, milk, onion, parsley, thyme, butter. Candidates are from the same food group and used in at least 100 recipes.
