What each ingredient does

Butter
Adds richness and flavour, and gives the sauce a smooth, glossy mouthfeel.
Flour
Thickens the sauce as it cooks with the liquid, forming a smooth roux.
Water
Forms the liquid base that the cooked flour thickens into a sauce.

The step that matters

Gradually add the water, stirring constantly. Adding liquid slowly while stirring keeps the starch dispersed, so the flour thickens the sauce smoothly without lumps.
