What each ingredient does

Rich, crumbly cheese
Melts into the sauce, providing the main flavor and a creamy, thick texture.
Rich milk
Forms the liquid base of the sauce, keeping it smooth and moist.
Butter
Adds fat for richness and helps the sauce feel smooth and velvety.
Thick toast
Gives a sturdy base that soaks up the sauce without falling apart.

The step that matters

Dissolving the cheese. Stirring constantly over medium heat keeps the cheese melting evenly. Cheese proteins tighten and clump, and fats can separate, when the pan is too hot or left unattended, leaving the sauce grainy or oily.
