Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base of the sauce and gives it a creamy body.
- Flour
- Thickens the milk as its starch swells when heated, giving the sauce body.
- Butter
- Adds fat for richness and a smoother mouthfeel in the sauce.
The step that matters
Stirring the flour mixture into boiling milk. Flour mixed into milk without sufficient stirring can clump, and starch only thickens fully once the mixture reaches a boil. Stir steadily as it goes in so the starch disperses evenly.
