What each ingredient does

Butter
Melts with the flour to form a smooth base and adds richness to the sauce.
Flour
Thickens the melted butter and milk or water into a smooth, cohesive sauce.
Milk or water
Forms the liquid that the flour thickens, giving the sauce its body.

The step that matters

Adding the liquid gradually while stirring. Adding the milk or water slowly while stirring constantly keeps the flour dispersed, so the sauce thickens smoothly instead of forming lumps.
