Sauerkraut

Sauerkraut is the winter larder in its plainest form. White cabbage is cut fine, salted, pressed under its own juice, and left until lactic acid does the work. No vinegar. Nicht aus dem Glas. The sourness is made by time and salt, not poured in from a bottle.

It belongs everywhere on the German table, but not in one way. In the north it sits beside smoked pork, sausages, and dark bread; in Swabia it meets Schupfnudeln, little rolled potato noodles; in the Palatinate and Alsace border country it goes into great cabbage-and-pork pots; in Bavaria it is often softened with onion, caraway, and a little apple. Im Norden anders, im Süden anders. Same cabbage, different stove.

The technique that decides it is submersion. Salt draws water out of the cabbage, and that brine must cover every shred because lactic acid bacteria work safely without air while mold wants the surface. Press it down, weight it, and check it. If the cabbage floats dry, you've made a compost bucket, not Sauerkraut.

Use a tight, heavy head of cabbage, cut it evenly, and weigh the salt at two percent of the cabbage weight. Then leave it alone at cool room temperature until it smells cleanly sour and tastes alive. Das braucht seine Zeit. Erst verstehen, dann kochen.
