What each ingredient does

Butter
Provides fat and richness, and softens into a creamy base that carries the sauce's flavor.
Flour
Thickens the sauce as its starch swells in the hot liquid, giving body to the finished sauce.
Boiling water
Forms the liquid of the sauce, which thickens as the flour starch swells in the heat.

The step that matters

Pouring in the boiling water while stirring well. Flour starch clumps when it meets hot liquid all at once. Stirring constantly disperses the granules evenly, so the sauce stays smooth and thickens without lumps.
