Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and rich flavour, and helps the flour blend smoothly into the sauce.
- Flour
- Its starch thickens the sauce as it heats in the melted butter and liquid.
- Milk
- Forms the liquid body of the sauce, which thickens as the starch swells.
- Thick cream
- Adds richness and a smoother, silkier texture to the finished sauce.
The step that matters
Adding the milk gradually while stirring. Flour starch coated in fat disperses evenly only if liquid is added slowly with constant stirring. Adding it all at once makes lumps that are hard to smooth out.
“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.
