Cassoeula (Lombardian — Pork Rib and Savoy Cabbage Stew)

Cassoeula is one of the most deeply Lombard of all winter dishes — a rich, abundant stew of pork ribs, cotenna (pork rind), sausage, and Savoy cabbage, braised together until the pork fat has rendered into the cabbage and the collagen from the rinds has thickened the broth to a glossy, unctuous consistency. It is emphatically cold-weather food, traditionally eaten in January after the first frost, which is said to sweeten the Savoy cabbage by converting its starches to sugars. The dish's name derives from the broad, flat wooden spoon (cassoeula) used to stir it during cooking. It belongs to the cucina povera tradition of Milan and its hinterlands, where the arrival of the pig-slaughtering season in late autumn produced an abundance of secondary cuts — the spareribs, trotters, ears, rinds, and sausages that were combined with the season's most abundant winter vegetable to make a single, sustaining pot. The cotenna (pork rind) is the dish's hidden genius: boiled separately until soft, cut into squares, and added to the braise, it dissolves partially during cooking and releases collagen that thickens and enriches the cooking liquor in a way that no other ingredient can. The preparation begins with rendering pancetta or lardo in a heavy casserole, then browning the pork ribs in batches. A soffritto of onion, carrot, and celery follows. White wine deglazes, then stock or water is added. The pork rinds (pre-boiled for 20 minutes) are added, then the outer cabbage leaves and finally the cut inner cabbage in the final 20–30 minutes. Sausages — usually luganega, a mild Lombard pork sausage — are added in the final fifteen minutes only. The whole braise cooks covered over low heat for 1.5–2 hours until the pork ribs are tender and falling from the bone. Served with soft, plain polenta.
