Warm the milk over medium heat you just want it to be warm, like around 110 F, not hot, and certainly not boiling.
Start by melting the butter in a saucepan over medium-low heat.
Stir in the flour.
Whisk in a little of the milk at a time, stirring continuously.
It will take up to 15 min for the liquid to thicken. It will be ready as soon as you have a smooth, slightly thick sauce.
