Ingredients

Directions

Prepare the sauce

  1. Flake the cold codfish using two forks.

  2. In a small pan, melt the butter and mix in the flour over heat.

  3. Add the water and stir until it boils and becomes a smooth sauce.

  4. Stir in the chopped parsley, mustard, salt, and pepper.

Assemble and bake

  1. In a pie dish, layer half of the fish, half of the sauce, and a handful of grated bread.

  2. Repeat with the remaining fish, sauce, and bread on top.

  3. Drizzle melted butter over the top and place in the oven to brown or warm through.

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

What each ingredient does

Codfish
Provides the main body and flaky texture of the pie.
Flour
Thickens the butter and water into a smooth sauce that binds the fish.
Butter
Adds richness and helps the topping brown in the oven.
Bread
Adds bulk and soaks up sauce, giving the layers body and a light crumb.

The step that matters

Making the sauce smooth. Flour must be cooked briefly in the melted butter before the water is added, and the mixture must be stirred while it boils. Stirring keeps starch granules dispersed so the sauce thickens without lumps.

Swap the mustard

How well each one fits the dish's main ingredients (butter, flour, parsley, pepper, bread):

  1. Shallotfits better
  2. Carrotfits better
  3. Chivefits better
  4. Mustardthe original

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