What each ingredient does

Brown flour: Browned flour thickens the milk and adds a toasted, nutty flavour.
Milk: Forms the creamy base of the soup and gives it body and richness.

The step that matters

Browning the flour. Flour must be cooked until deep golden so its starch and sugars toast and develop flavour. Undercooked flour tastes raw and pasty, while overbrowned flour turns bitter.
