Kiseli Kupus

The story

Kiseli kupus—whole heads of cabbage salted and fermented in large barrels over the course of the fall—is the foundation without which sarma, whether the Serbian or Croatian, Polish or Hungarian version of the same idea, simply does not exist. The work begins months before Christmas: whole heads are packed into a wooden or plastic barrel, sprinkled with salt, and pressed down under a weight, then left to ferment for weeks in a cool place, developing the distinctive sourness that gives sarma its characteristic note. This method of preserving vegetables for the winter was shared across nearly all of Central and Eastern Europe in the days before refrigerators made fresh produce available year-round. Beyond sarma, fermented cabbage is also eaten on its own, as a side dish or a salad. For Serbian families in the diaspora, where fermenting whole heads of cabbage in a barrel is a rarer practice than in the old country, the store-bought kind seldom fully replaces the flavor of homemade—a difference the older generations notice right away.
