Baked Codfish

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Soak, boil, and pick the salt codfish as you would for fish balls.

  2. Add an equal quantity of mashed or chopped potatoes, a large piece of butter, and enough warm milk to make it soft.

Bake and serve

  1. Transfer the mixture to a buttered dish, rub butter over the top, and sprinkle with sifted flour.

  2. Bake at 400°F (200°C) for about 30 minutes, until rich brown.

  3. Serve with drawn butter sauce and sliced hard‑boiled eggs.

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

What each ingredient does

Salt codfish
Provides the main flavour and the flaked body of the dish.
Potatoes
Add starch and bulk, giving the mixture a soft, creamy texture.
Warm milk
Adds moisture so the mixture becomes soft and spreadable.
Butter
Adds richness and helps the top brown in the oven.
Sifted flour
Dusted on top, it helps the surface brown and form a light crust.

The step that matters

Bake until rich brown. Baking at 400°F until the top is rich brown develops browning through the Maillard reaction. Removing it too early leaves the top pale and the flavour flat.

Swap the potato

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

  1. Potatothe original
  2. Arrowrootfits about as well
  3. Leekfits less well
  4. Shallotfits less well

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