Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codfish
- Provides the flaked body and mild flavour that the sauce carries.
- Butter
- Adds fat and richness, and forms the base of the roux.
- Flour
- Thickens the sauce as its starch swells in the hot butter and milk.
- Milk
- Forms the liquid of the sauce, which thickens as the starch sets.
- Toast
- Gives a crisp base that holds the creamed sauce.
The step that matters
Adding the milk gradually. Pouring milk in slowly while stirring lets the flour disperse evenly in the roux. Added all at once, the starch clumps into lumps that stay in the finished sauce.
