Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melts with the flour to form a roux, adding richness and a smooth base for the sauce.
- Flour
- Its starch thickens the liquid as it heats, giving the sauce body.
- White stock
- Provides the main savoury liquid that flavours the sauce.
- Hot milk
- Adds creaminess and a mellow flavour while thinning the sauce.
The step that matters
Allow the mixture to boil while stirring. Flour starch only thickens fully once it reaches a boil and swells. Constant stirring keeps the flour dispersed so lumps do not form and the sauce does not scorch on the bottom of the pan.
“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.
