What each ingredient does

Stock espagnole
Forms the base of the sauce, providing body and the main savoury flavour.
Essence of mushrooms
Adds concentrated mushroom aroma and savoury depth to the sauce.
Blond of veal
Clarifies the sauce, helping it become clear and smooth as it simmers.

The step that matters

Simmer gently until the sauce clarifies. Boiling the sauce hard can cloud it and break up the proteins that the blond of veal is binding together. A gentle simmer lets the clarifying agent collect impurities so they can be removed when the sauce is strained.
