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 flavour and the flaky body of the dish.
- Butter
- Adds richness and fat, carrying flavour through the sauce.
- Flour
- Thickens the butter and milk into a smooth, stable cream sauce.
- Milk
- Forms the liquid base of the cream sauce and gives it its creamy texture.
- Eggs
- Add richness and help bind the sauce as they set gently with heat.
The step that matters
Stir until boiling, then add the codfish. Flour must be cooked smooth into the butter and milk to thicken the sauce fully. Lumps are hard to remove later, so stirring steadily while the sauce comes to a boil keeps it even and creamy.
