Saure Kutteln

Saure Kutteln are Swabian table food, old Arme-Leute food, poor-people cooking, and still one of the clearest proofs that Weggeworfen wird nichts, nothing gets thrown away. The tripe is already cleaned and cooked by the butcher, then cut into strips and carried by a sour brown sauce, vinegar, onion, broth, and a good splash of Trollinger if the bottle is open. Set it down with Bratkartoffeln, fried potatoes, and nobody needs a speech.

Swabia keeps the dish sharp and brown, with a flour roux cooked properly dark before the liquid goes in. Baden often leans more on wine. In Franconia and Bavaria you find sour offal too, but the pot changes, sometimes lung, sometimes creamier, sometimes less vinegar. Im Norden anders, im Süden anders. This is not one national offal stew with a flag stuck in it.

The deciding technique is the roux. Cook the flour in fat until it smells nutty and turns chestnut brown, because pale flour gives you paste and burnt flour gives you bitterness. Then add the liquid slowly, whisking hard, so every spoon of flour drinks before the next splash comes in. That is the difference between a smooth sour sauce and a pot of lumps. Nicht aus dem Glas.

The tripe only needs gentle heat after that. It is already cooked, so a hard boil tightens it and makes it squeak under the teeth. Runter mit der Temperatur, let it move quietly until the strips are soft and the vinegar has settled into the sauce. Das braucht seine Zeit, but not all night.
