A Soup-Stew of Beans and Cavolo Nero

The soup-stew, a bowl of spoon-tender meat, beans, and aromatics that partly collapse into the surrounding stock, is one of the suppers I hold dearest. More often taken as lunch, this is food that feeds the soul as much as the belly, enriching, calming, quietly energizing. This is the cooking on which to lavish the cheapest cuts going, the fatty, bony lumps that butchers sell at reduced prices: mostly cuts from the neck and lower legs. Ingredients whose sole purpose is to give body to the liquid in which they cook. A knuckle end of prosciutto would be a sound addition here, if your local deli will sell you one. Most will charge very little. Butchers are an excellent source of ham bones with much meat attached. Failing that, I use a lump of ham, complete with its thick layer of fat.
