Ingredients
Directions
Prepare the fish
Boil a fresh cod fish or trout or white fish weighing from four to five pounds.
Pick out all the bones and skin.

Add a little grated nutmeg, a teaspoonful of salt and one fourth teaspoonful of white pepper or a pinch of red pepper.
Place over a quick fire in double boiler and stir constantly till it forms a thick paste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the milk into a smooth sauce that holds the fish together.
- Milk
- Forms the liquid base of the sauce, which thickens as the flour cooks.
- Egg yolks
- Enrich the sauce with fat and help it set and bind when baked.
- Butter
- Adds richness and flavor to the sauce and helps it feel smooth.
- Fish (in the method)
- Forms the main body of the dish, layered with the sauce.
The step that matters
Cooking the sauce to a thick paste. Flour must be cooked with the milk over steady heat while stirring constantly, or it stays pasty and lumpy. Stirring prevents scorching and lumps, so the sauce thickens evenly before the egg yolks are added.
Swap the white pepper
How well each one fits the dish's main ingredients (milk, flour, oyster, cream, onion, thyme, parsley):
- Marjoramfits better
- Nutmegfits better
- Celeryfits better
