What each ingredient does
- Cold water
- Forms the liquid that the flour thickens into a smooth sauce.
- Flour
- Its starch swells in the hot liquid and thickens it.
The step that matters
Blend fully before heating. Flour mixed into cold liquid and stirred until smooth stays dispersed as it heats. If it is left lumpy or not fully combined, the starch clumps and cooks unevenly, leaving lumps in the finished thickener.
