Epicurean Croquettes

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. Soak the finnan haddie in equal parts milk and water for 1 hour.

  2. Preheat the oven to 350°F (175°C).

  3. Bake the haddie for 30 minutes.

  4. Drain the haddie.

  5. Separate the haddie into flakes; you should have about 1¾ cups.

Make the filling

  1. Cook the shallot, green pepper, and red pepper in butter for 5 minutes.

  2. Add the flour and 1 cup of milk. Stir until smooth.

  3. Stir in the flaked finnan haddie, salt, paprika, and pepper.

  4. Cool the mixture.

Shape and fry

  1. Shape it into croquettes.

  2. Coat with breadcrumbs.

  3. Fry until golden.

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

What each ingredient does

Finnan haddie
Provides the main smoky, flaky fish body of the croquettes.
Butter
Adds fat and richness and cooks the vegetables gently without browning.
Flour
Thickens the milk into a smooth binding sauce that holds the filling together.
Milk
Forms the creamy base of the sauce, adding moisture and softness.

The step that matters

Cool the mixture before shaping. A warm, loose filling is too soft to hold its shape. Chilling lets the starch in the flour-thickened sauce set, so the croquettes keep their form and do not break apart when fried.

Swap the shallot

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

  1. Potatofits better
  2. Capsicumfits better
  3. Chivefits about as well
  4. Shallotthe original

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