Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Fat that coats the flour, adding richness and a silky mouthfeel to the sauce.
- Flour
- Starch that thickens the liquid into a sauce as it heats and swells.
- Milk
- Liquid that forms the body of the sauce, with cream adding extra richness if used.
The step that matters
Pour in the boiling milk while stirring briskly. Flour starch clumps when hot liquid hits it unevenly. Stirring vigorously as the milk goes in disperses the starch so the sauce thickens smooth instead of lumpy.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
