Thickened Gravy

Jus lié à la fécule teaches one clean lesson: the stock supplies the flavor, and the fécule supplies only the body. Before you touch the pan, know this: cold starch must meet boiling liquid while the whisk moves briskly. That meeting gives you a smooth, glossy sauce; hesitation gives you lumps.

The original assumed a saucier beside a stockpot never off the fire, binding a pint whenever service called. The source already provides a compact one-pint working ratio; for a useful make-ahead batch, it is multiplied fourfold to about two quarts, still modest beside a rolling brigade reserve and manageable in one saucepan. The constant stockpot and dedicated saucier are scaffolding and can go. The boiling stock, cold slurry, and brisk stirring are the dish and must stay. One cook, one stove, one evening.

Done properly, the jus lié remains clean-tasting and lightly translucent, with enough body to cling to poultry or meat without burying it. There is no roux because the source does not want one. Have the stock fully boiling and the slurry freshly stirred before they meet; that single moment decides the sauce.
