Hessische Kartoffelsuppe

Hessische Kartoffelsuppe sits in the middle of Hesse's cold-weather table: floury potatoes, leek, celeriac, carrot, marjoram, and Frankfurter Würstchen sliced through the bowl. It's weeknight Hausmannskost, honest home cooking, but it also turns up on a Sunday when the purse is thin and the pot needs to feed the table. Hesse is not pretending to be Bavaria here. Das ist kein Bierzelt.

Every region makes Kartoffelsuppe, and every region thinks its pot is sensible. In Hesse I want soup greens and marjoram, sometimes a little Speck underneath, sometimes not, with the Würstchen warmed at the end. Farther north the pot often tastes smokier; farther south it can be rounder with cream or butter. Im Norden anders, im Süden anders.

The technique is simple and it decides the soup: mash only part of the potatoes into the broth and leave the rest in chunks. Floury potatoes release enough starch to bind the soup without cream, but a blender tears the starch loose too hard and gives you paste. Mash by hand, gently. The spoon should find both broth and potato, not baby food.

Use the larder properly. Leek tops, parsley stems, a smoked rind if you have one, they belong in the pot or the stock, not in the bin. Weggeworfen wird nichts. Salt only at the end, because stock, Speck, and Würstchen all bring their own. Erst verstehen, dann kochen.
