Creamed Codfish
Ingredients
Directions
Prepare
Soak the salt fish in cold water overnight, then drain and separate into very small pieces.
Make the creamed codfish
In a double boiler, heat the milk until boiling.
Add the drained codfish to the boiling milk and cook for 10 minutes.
Melt the butter in a separate pan, add the flour, and stir until smooth.
Stir the butter and flour mixture into the milk until creamy.
Add the beaten egg, stir well, and serve immediately without further cooking.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt fish
- Provides the main flavor and the flaky texture of the dish.
- Milk
- Forms the liquid base that becomes the creamy sauce.
- Butter
- Adds richness and carries flavor when cooked with the flour.
- Flour
- Thickens the milk into a smooth, creamy sauce.
- Egg
- Adds richness and some body to the finished sauce.
The step that matters
Stirring the butter and flour mixture into the milk. Flour thickens only when it is evenly dispersed in liquid. Stirring it smooth before and while adding it to the hot milk helps prevent lumps and gives an even, creamy texture.
