Bockwurst im Brötchen

Bockwurst is Berlin weeknight food with a tavern birth certificate. A pale, plump Brühwurst, a scalded sausage, warmed and eaten with mustard, bread, and the beer it was named beside. This is not a grill sausage. Treat it like one and the skin bursts, the fat runs out, and you've bought flavour just to pour it down the sink.

Berlin and Brandenburg keep it close to the kettle and the snack counter. Elsewhere the sausage shifts: in the south it may be smokier or closer to a Weisswurst cousin, in the north it might sit beside potato salad or kraut. Im Norden anders, im Süden anders. The Berlin point is simple: hot sausage, sharp mustard, good roll, no theatre.

The technique is the dish. Bring the water up, then runter mit der Temperatur, down with the temperature, to about 75C. The sausage is already cooked, so you are heating it through, not cooking it again. Boiling tightens the casing too hard and drives out the fat. Gentle water keeps the snap, the juice, and the seasoning where they belong.

Use proper Bockwurst from a butcher if you can, pork and veal or all pork, lightly smoked if that's the local style. The mustard is sharp, the roll is crisp, and the kraut, if you use it, is warmed from the larder. Nicht aus dem Glas only when the jar is pretending to be a sauce. For mustard, the jar is its home. Schön ist, was schmeckt.
