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 savory flavor and salty fish character of the dish.
Milk
Forms the liquid base of the creamy sauce.
Flour
Thickens the milk so it becomes a smooth, body-rich sauce.
Egg
Adds richness and helps thicken the sauce as it cooks.

The step that matters

Add the beaten egg to the milk mixture. Eggs can curdle or scramble if the mixture is too hot or added without stirring. Adding the egg to a thickened milk base and stirring keeps it smooth and creamy.
