What each ingredient does

Flour
Thickens the sauce and, browned in butter, adds a nutty depth of flavour.
Butter
Adds fat and richness and helps the flour brown in the pan.
Brown stock
Forms the liquid base of the sauce and carries its savoury flavour.
Mushrooms
Add earthy flavour and body to the sauce.

The step that matters

Stirring the flour into the butter until well browned. Flour and fat cook together to form a roux. Cooking it until browned develops nutty flavour, but it can scorch quickly over medium heat, so stir constantly. Adding stock to a roux cooked this way also helps it blend smoothly without lumps.
