The Gravy of Roasts

Jus de rôtis teaches the cleanest law in sauce making: the brown film in the roasting pan is concentrated roast, not washing-up, and it must be loosened before it burns. The fat and juices may set into a dark lacquer, but they must never cross into black. Keep a little of the fat in the finished jus, because its savour lives there and this is not a consommé.

The old formula assumed a roast turning on a spit, a dripping pan only just large enough, a saucier minding stock from matching bones for hours, and a stockpot never off the fire. A salamander has no work here. For one cook, one stove, one evening, roast the bones in an ordinary roasting pan, strain through a damp cloth instead of professional muslin, then wash the roast pan with a manageable splash of stock and finish the full reduction in a wide saucepan. That transfer is scaffolding for home equipment; roasting the bones, deglazing the pan, reducing by half, and leaving a trace of fat are the dish and must stay. The brigade volume has been scaled to about 2 quarts, enough for a large holiday table with some left for the freezer, without changing the method or the reduction ratio.

Before you touch the pan, choose one that hugs the roast. Exposed fat in an oversized pan scorches while the meat cooks, and no amount of fine stock can sweeten a black fond afterward. Protect the browning. That choice decides the jus before any liquid enters it.
