Cream Fish

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

  1. Boil the cod or halibut and break it into small pieces while hot.

  2. Add butter, pepper, and salt to the fish.

Make the sauce

  1. In a saucepan, boil the milk with the onion and ¼ pound of butter.

  2. Thicken the milk mixture with flour and let it boil.

Assemble and bake

  1. Layer the fish and sauce in a dish until filled.

  2. Top with breadcrumbs, bits of butter, and lemon juice.

  3. Brown in the oven at 350°F (175°C).

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

What each ingredient does

Cod or halibut
Forms the main body of the dish, flaking into tender pieces when cooked.
Milk
Forms the base of the creamy sauce that moistens the fish.
Flour
Thickens the milk so the sauce clings to the fish instead of running off.
Butter
Adds richness and fat, carrying flavor and helping the top brown.
Breadcrumbs
Form a crisp topping that browns in the oven.
Lemon juice
Adds acidity that brightens the rich sauce and fish.

The step that matters

Thicken the milk mixture with flour. Flour must be cooked into the hot milk and boiled so its starch swells and thickens the sauce; if it is added to cold liquid or not boiled, lumps form and the sauce stays thin and floury.

Swap the onion

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

  1. Arrowrootfits better
  2. Shallotfits better
  3. Potatofits better
  4. Onionthe original

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