Ähzezupp (Kölsche Erbsensuppe)
The Cologne pea pot earns its depth from soaked peas and cured pork bone, simmered slowly until the soup thickens itself and the meat falls clean from the knuckle.

Swabia's Filder plateau puts its pointed cabbage to work here: smoke, floury potatoes, and Spätzle in one pot, with Röstzwiebeln over the top because even a weeknight deserves the crunch.
Fildereintopf belongs to the Filder plateau south of Stuttgart, where the pointed Filderkraut grows sweeter and more tender than the round white cabbage most people throw into a pot. This is market-garden cooking: cabbage from the field, floury potatoes from storage, a piece of smoked pork from the larder, and Spätzle, small Swabian egg noodles, because Swabia will put flour and egg to work before it lets a thin broth stand alone.
Im Norden anders, im Süden anders. The north would lean cabbage toward kale, sausage, or the sharpness of the fish table; the Rhineland would sweeten and sour a pot its own way. Here the argument is Swabian: Filderkraut, Kassler, smoked cured pork, potatoes that soften at the edges, and Röstzwiebeln, fried onions, on top. Das ist kein Bierzelt. It's a weeknight pot that can sit proudly on Sunday if the broth is clean and the onions are dark gold.
The technique is simple and it decides the dish: sweat the cabbage in the pork fat before you add the liquid. Salt pulls water out of the cabbage, the fat carries the smoke and caraway, and the leaves collapse into their own sweet juice. Drown raw cabbage in stock and you get a watery pot with green shreds floating in it. Cook it first and the stew tastes of the field, not the tap.
Keep the Spätzle for the end. They are already cooked, and if you leave them in the pot for half an hour they swell, drink the broth, and turn the whole thing dull. Würzen, Fett, Salz zum Schluss, season, fat, salt at the end: taste after the smoked pork has given up its salt, sharpen with a spoon of vinegar, then the Röstzwiebeln go over. Schön ist, was schmeckt.
Filderkraut is the pointed cabbage of the Filder plateau south of Stuttgart, and written references to its cultivation in the region reach back to the 18th century. The name Filderkraut/Filderspitzkraut was registered by the European Union as a protected geographical indication in 2012, tying the cabbage to the loess soils and market-garden villages that supplied Stuttgart. This Eintopf is the household form of the same larder logic: stored potatoes, smoked pork, and leftover Spätzle stretching fresh cabbage into a full Swabian pot, not a national formula.

Toss the sliced onions with the flour only when the pot is ready; flour left sitting on wet onion turns to paste. Heat 2 tablespoons of the lard in a heavy pot over medium heat and fry the onions, stirring often, until deep gold and crisp at the edges, 10 to 12 minutes. Lift them out with a slotted spoon and leave the fat in the pot, because that onion fat is the first seasoning for the stew.
Add the remaining tablespoon of lard, then the diced Speck and any rind. Let it render gently for 5 to 7 minutes; if you blast cured pork with hard heat, it tightens before the fat has done its work. Add the diced onion and cook until it turns glassy, scraping up the browned flour and onion bits from the bottom. Weggeworfen wird nichts.
Stir in the caraway, juniper, cabbage ribbons, and a small pinch of salt, then turn everything through the pork fat. Cover the pot and let the cabbage sweat for 8 to 10 minutes, stirring once or twice, until it turns glossy and collapses by a third. This is the step that decides the stew: salt draws the cabbage's own water, fat carries the smoke, and the leaves sweeten before stock can wash them flat.
Add the potatoes, Kassler, bay leaf, marjoram, and stock, using just enough liquid to come level with the cabbage and potatoes. Bring it to a quiet bubble, then runter mit der Temperatur, down with the temperature, and simmer partly covered for 25 to 30 minutes, until the potatoes are soft at the edges and the pork is cooked through. A hard boil tears the cabbage and tightens the smoked pork; a low simmer lets the floury potatoes thicken the broth by themselves.
Remove the bay leaf and any large piece of rind. Stir in the cooked Spätzle and simmer 3 to 4 minutes, only until they are heated through and still separate. They go in late because they are already cooked; leave them longer and they swell, drink the broth, and make the pot dull. Taste now, then add black pepper, the vinegar, and salt only if the smoked pork has not already done enough.
Ladle the stew into deep bowls, making sure every bowl gets cabbage, potato, pork, and Spätzle. Spoon a little of the broth over the top, scatter with the Röstzwiebeln and chives if you're using them, and put the rest of the onions on the table so they stay crisp. Schön ist, was schmeckt.

The Allgäu's Alpine cheese soup works only if the Bergkäse melts gently off the heat, where it turns smooth instead of stringy.

A firm egg dough, grated into tiny crumbs and cooked in clear broth: Allgäu kitchen thrift, warm in the bowl, and finished only when the Riebele keep their bite.

The Altmark wedding broth is a clear soup with no tricks: bones for depth, patient skimming for clarity, and small semolina dumplings that make it festive.
