Berlin Currywurst
The Berlin Imbiss counter on a plate: fried sausage cut thick, a tomato curry sauce cooked until glossy, and enough fries or bread to chase every bit.

Blaue Zipfel (Saure Zipfel)
Created by
Franconia's sour-poached bratwurst skips the grill: raw sausages, onion, vinegar, wine, and one quiet rule, keep the sud below the boil.

Blaue Zipfel belong to Franconia, especially around Nuremberg, Bamberg, and the old Wirtshaus tables where a sausage does not always need a grill to prove itself. Raw bratwurst goes into a sharp Sud, a poaching liquor of vinegar, white wine, onion, bay, and spice, and comes out pale blue-grey at the skin. That colour is the dish. Don't apologise for it.
Im Norden anders, im Süden anders. The north has its fish and rye, the Rhineland its sweet-sour roasts, Swabia its dumplings; Franconia has a serious sausage culture and knows when not to brown one. Some cooks make the sud sharper with more vinegar, some softer with more wine, and some add carrot or leek. I keep it clean: onion, bay, pepper, juniper, a little sugar to round the acid, and good raw bratwurst.
The rule is simple. Boil the sud first so the onion softens and the spices give themselves up, then turn the heat down before the sausages go in. If the liquid boils around raw bratwurst, the casings split and the fat runs out into the pot. Gentle poaching sets the meat, tightens the skin, and lets the vinegar do its work without turning the sausage dry. Erst verstehen, dann kochen.
Serve them in the liquor with the onions, mustard or horseradish, and rye bread to catch the sour broth. Weggeworfen wird nichts. The sud is not a bath to throw away; it's half the plate.
Blaue Zipfel are recorded as a Franconian Wirtshaus dish tied to the region's bratwurst towns, especially Nuremberg, whose small protected Nürnberger Rostbratwurst was first regulated by city ordinance in the early 14th century. The blue-grey colour comes from the fresh sausage casing reacting in the acidic vinegar-and-wine sud, not from smoking or dye, which is why the dish needs raw bratwurst rather than precooked sausage. The name shifts by town and table: Blaue Zipfel stresses the colour, while Saure Zipfel stresses the sour liquor.
The technique, the tradition, and the story behind every dish.

Instructions
- 1
Build the sud
Put the water, wine, vinegar, onions, carrot, bay, peppercorns, juniper, cloves, mustard seeds, sugar, and salt into a wide pot. Bring it to a boil, then lower it and simmer 15 minutes, because the onion needs time to soften and the spices need time to season the liquid before the sausages arrive.
- 2
Lower the heat
Turn the heat down until the sud only trembles. Runter mit der Temperatur. Raw bratwurst is delicate; a hard boil bursts the casing, pushes out the fat, and leaves you with dry meat and a cloudy pot.
- 3
Poach the sausages
Slide the raw bratwursts into the hot sud in one layer, or as close to one layer as your pot allows. Poach gently for 15 to 18 minutes, turning once, until the sausages are firm, pale, and blue-grey at the casing. The acid sets the skin and seasons the meat from the outside in; it is not there for decoration.

Taste and serve
Taste the sud and adjust with a pinch of salt or a small splash of vinegar. Würzen, Fett, Salz zum Schluss, because the sausages give up seasoning as they cook and you won't know the balance until the end. Serve two or three sausages per bowl with plenty of onions and a ladle of the sour liquor, with rye bread, horseradish, or mustard beside it.
Chef Tips
- •Use raw fresh bratwurst, not smoked, cooked, or grilled sausage. The dish depends on the raw casing tightening in the acidic sud; a precooked sausage only warms through and never becomes Blaue Zipfel.
- •Keep the pot below the boil once the sausages go in. If you see the liquid rolling hard, you've gone too far, and the fat will leave the sausage for the broth.
- •White wine vinegar gives the cleanest sourness. Plain distilled vinegar is too hard here; apple vinegar works if you want a softer edge, but keep the Franconian shape of the dish.
- •Serve the onions and broth. Nicht aus dem Glas, and not down the drain either. The sour onion liquor is what turns a few sausages and bread into supper.
Advance Preparation
- •The sud can be made up to one day ahead and chilled with the onions and spices in it; reheat it and lower it below the boil before adding the raw sausages.
- •Poach the sausages just before serving. Reheated bratwurst tightens and dries, which is poor thanks for a good sausage.

Bockwurst im Brötchen
A Berlin Brühwurst belongs in hot water, not boiling water: warm it gently, keep the skin tight, then eat it in a roll with sharp mustard.

Fränkische Bratwurst
Franconia's everyday sausage lives by a gentle poach and a slow brown, so the casing snaps, the pork stays juicy, and the marjoram comes through clean.

Frankfurter Würstchen
The Frankfurt sausage lives by one quiet rule: warm it in water that no longer boils, or the sheep casing bursts and the smoke you paid for runs into the pot.
