Saucisses de Francfort et de Strasbourg

Saucisses de Francfort et de Strasbourg (Frankfurt and Strasbourg sausages) teach restraint at its most useful. The one true thing to know before touching the pan is this: the water begins at a boil, but the sausages must not continue boiling. A gentle poach warms the filling while keeping the casings taut and the meat juicy; another few careless minutes make both varieties tough.

The original entry assumes a professional service pantry, with fully cooked sausages from the charcutier, a generous saucepanful of water, and braised choucroute already waiting beside the stove. At home, a four-quart pan, eight sausages, and a small pot of prepared choucroute are the honest equivalents. Scaling down the service is scaffolding and can go. The brief poach is the dish and must stay. One cook, one stove, one evening.

When they are right, the sausages feel plump beneath the tongs, their casings smooth and intact, with no fat leaking into the water. If the water boils again, move the pan off the heat at once; ça se rattrape when caught quickly. Lowering the heat the instant the sausages enter is the step that matters most.
