Codfish Omelette with Two Eggs

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 base

  1. Boil the codfish and potatoes together until cooked.

  2. Add the butter, milk or cream, and one beaten egg to the mixture.

Bake and finish

  1. Bake in a preheated oven at 350°F (175°C) for 10 minutes.

  2. Remove from the oven, then pour the second beaten egg mixed with 1 teaspoon of cream over the mixture.

  3. Return to the oven for about 5 minutes.

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

What each ingredient does

Codfish
Provides the main flavour and flaked texture of the omelette.
Potatoes
Add body and starch that help bind the mixture together.
Eggs
Set when heated, giving the omelette its structure.
Milk or cream
Adds moisture and softness to the set egg.
Butter
Adds fat for richness and a softer mouthfeel.

The step that matters

Returning the omelette to the oven after adding the second egg. Egg proteins set as they heat. Too much time or heat past that point makes the egg tough, dry and rubbery, so it should be checked closely during the final 5 minutes.

Swap the potato

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

  1. Potatothe original
  2. Asparagusfits about as well
  3. Chivefits less well
  4. Leekfits less well

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