Slowly add the beaten raw egg, mixing well.
Season with salt and pepper to taste.
Serve
Pour the sauce over the boiled codfish or serve in a sauce-tureen.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, and gives the flour a base to cook into.
- Flour
- Thickens the milk into a smooth sauce as it cooks.
- Milk
- Forms the liquid base of the sauce, which thickens as it heats.
- Hard-boiled egg
- Adds chopped egg texture and rich flavor to the sauce.
- Raw egg
- Enriches and gently thickens the sauce when stirred in off the heat.
The step that matters
Adding the raw egg. Raw egg can scramble if it meets very hot sauce or is added too fast. Removing the pan from heat first and adding it slowly while mixing keeps the sauce smooth.
