Eisbein mit Erbspüree und Sauerkraut

Eisbein is Berlin food first: cured pork knuckle, yellow pea puree, sauerkraut, mustard on the side. It belongs to the cold months and the city Kneipe table, the plate you set down when the larder is doing its work: salted pork, dried peas, fermented cabbage. Weggeworfen wird nichts, the bone and rind are not scraps here. They are the dish.

The argument starts at the regional line. Berlin and Brandenburg simmer the cured knuckle until the meat loosens and the rind turns soft. In Bavaria and Franconia they want Schweinshaxe roasted, blistered, and crisp. Im Norden anders, im Süden anders. This is not the beer-tent roast. Das ist kein Bierzelt.

The one technique is the heat. Keep the pot below a hard boil, just a quiet trembling simmer, because cured pork tightens fast when it is bullied. Boil it hard and the meat goes stringy, the rind splits, and the broth turns cloudy. Cook it gently and the collagen melts into the liquor, the bone gives, and the meat stays juicy enough to pull apart with a spoon.

Salt last. The Eisbein brings plenty from the cure, the kraut has its own, and the peas drink more than you think. Taste before you season. Erst verstehen, dann kochen.
