Ingredients

Directions

The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the codfish

  1. Soak the salt codfish overnight in just enough water to cover.

  2. Press dry and chop the codfish very fine.

Make the batter

  1. In a saucepan, heat the milk until it comes to a boil.

  2. Stir in the flour and butter until well combined.

  3. Add the beaten eggs and mix thoroughly.

Bake

  1. Pour the mixture into a buttered dish.

  2. Bake in a hot oven at 400°F (200°C) until it rises and browns on top.

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 savoury flavour and substance of the omelette.
Eggs
Set when heated, giving the omelette its structure and rise.
Milk
Adds moisture and softness to the mixture.
Flour
Thickens the milk mixture so it holds together after baking.
Butter
Adds richness and fat, helping the top brown.

The step that matters

Bake until it rises and browns on top. Eggs set as they heat, and the proteins trap air so the dish puffs. Taking it out too early leaves it flat and wet in the centre, while baking too long dries it out and makes it tough.
