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.

The Rhineland potato pancake lives by one plain rule: grate the potato, wring it dry, keep the starch, then fry it fast enough to crisp before it drinks the pan.
Rievkooche are Rhineland food, strongest around Köln, and they belong wherever people are hungry now: weeknight pan, market stall, church fair, Christmas market. In standard German they're Reibekuchen, in Bavaria Reiberdatschi, elsewhere Kartoffelpuffer. Im Norden anders, im Süden anders. Some eat them with apple sauce, some with sour cream, some with smoked fish. In Köln I put Rübenkraut beside them, the dark sugar-beet syrup, because the sweet bitterness against salty fried potato is the whole point.
The technique is not mysterious. Grate floury potatoes, wring them hard, and let the juice sit so the starch falls to the bottom. Pour off the brown water and put that white starch back into the batter. Leave the water in and the pancake steams soft; throw the starch away and it won't hold. Weggeworfen wird nichts, especially not the part doing the work.
Fry in enough hot fat that the edges start talking as soon as the batter hits the pan. Too little fat and you get leathery potato. Too cool and you get grease. Keep the pancakes thin, salt them when they come out, and eat them while the edges still crack under your teeth. Nicht aus dem Glas does not apply to Rübenkraut here; that jar is the made larder, boiled beet juice reduced until dark. The packet mix can stay on the shelf.
Potatoes entered German field cooking slowly after the eighteenth century, pushed in Prussia by Frederick II's potato orders in the 1750s, and grated potato pancakes became a cheap way to turn a winter cellar crop into a filling meal. Rübenkraut belongs especially to the Rhineland and Lower Rhine sugar-beet belt; beet sugar expanded after Franz Carl Achard opened the first industrial beet-sugar factory in Silesia in 1801, and the syrup remained a farmhouse larder product where beets grew well. The regional split is still plain: Köln and the Rhineland know Rievkooche with Rübenkraut or apple sauce, while southern Reiberdatschi usually lean apple sauce and keep the beet syrup off the plate.

Grate the potatoes and onion on the coarse side of a box grater into a bowl. The onion goes in with the potato because its juice helps slow browning, and the coarse grate gives you ragged edges that fry crisp instead of turning into paste.
Tip the grated mixture into a clean kitchen towel and squeeze hard over a bowl until the potato feels damp, not wet. Let the liquid stand for 5 minutes, then pour off the brown water and keep the white starch settled at the bottom. That starch goes back in because it binds the pancake; the water stays out because it would steam the pan soft.
Return the dry potato and onion to the bowl with the saved starch, eggs, salt, pepper, and nutmeg. Mix with a fork until the potato is just coated. If the bowl looks wet after a minute, spoon off the loose liquid; a wet batter makes a soft pancake, and that is not the dish.
Put a heavy skillet over medium-high heat and add enough lard, clarified butter, or oil to cover the base by about 5mm. The fat is ready when a shred of potato sizzles at once and turns pale gold in under a minute. Too cool and the potato drinks grease; too hot and the outside burns before the centre cooks.
Drop heaped spoonfuls of batter into the fat and press each one thin, about 1cm. Fry 3 to 4 minutes per side until the edges are crisp and deep golden and the middle no longer looks raw. Do not crowd the pan, because crowded pancakes lower the heat and start steaming each other. Runter mit der Temperatur only if the edges brown before the centre sets.
Lift the pancakes onto a rack or paper towels and salt them while the surface is still glossy with fat, because the salt clings now and wakes up the potato. Serve at once with Rübenkraut spooned alongside or lightly streaked over the edge. Sweet against salt. Schön ist, was schmeckt.

The Rhenish potato pot-cake for St. Martin's night: raw grated potatoes, bacon, onion, and sausage baked slowly until the middle sets and the edge turns dark and crisp.

The Rhenish pork knuckle that belongs to the Brauhaus table: cured, simmered gently, set on sour cabbage, and served with potatoes that catch every spoon of broth.

Cologne's joke of a sandwich has no chicken in it: just a rye Röggelchen, Gouda cut thick, mustard, onion, and gherkin, built cold so every bite stays sharp.
