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
Boil the fish until cooked.
Remove the bones and flake the fish.
Make the sauce
Combine milk, thyme, parsley, and onion in a saucepan.
Simmer the mixture until well flavored.
Wet the flour with a little water.
Stir the wet flour into the milk mixture along with the butter.
Cook the mixture until thickened.
Strain the sauce over the egg yolks and mix well.
Season the sauce with pepper and salt.
Assemble and bake
Layer sauce and fish in a pudding dish, repeating until full, finishing with sauce on top.
Cover the dish with rolled crackers.
Sprinkle grated cheese over the crackers if desired.
Bake in a preheated oven at 350°F (175°C) until browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White fish
- Forms the flaky body of the dish, holding its shape in layers with the sauce.
- Milk
- Forms the base of the sauce, providing moisture and a creamy texture.
- All-purpose flour
- Thickens the milk into a smooth sauce when cooked.
- Butter
- Adds richness and fat, giving the sauce a smooth, rounded flavor.
- Egg yolks
- Enriches and thickens the sauce, adding body and richness.
The step that matters
Cook the mixture until thickened, then add the egg yolks. Egg yolks thicken when heated gently; if the sauce is too hot when they are stirred in, they can scramble, leaving a grainy texture. Cook the flour sauce fully first so it is smooth before adding the yolks.
Swap the onion
How well each one fits the dish's main ingredients (fish, milk, thyme, parsley, flour, butter, egg):
- Shallotfits better
- Leekfits better
- Potatofits better
- Onionthe original
Fit is the average pairing score against fish, milk, thyme, parsley, flour, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
