Zuppa di Castagne e Cavolo Nero
Cavolo nero is a member of the kale family. Between farm stands, specialty produce markets, and natural foods stores it is available year-round. To find it, be aware of its many aliases: Tuscan kale, black cabbage, lacinato, and dinosaur kale. Its rich, sweet, almost meaty flavor will have you hooked from the first bite.
Cooks' notes:
·Soup can be made 3 days ahead and cooled completely, uncovered, then chilled, covered. Reheat, thinning with water as necessary.
·Beans can be soaked at room temperature up to 12 hours.
·To quick-soak beans: Cover beans with cold water by 2 inches in a 4- to 5-quart pot and bring to a boil, uncovered. Boil beans 2 minutes, then remove from heat and let stand, uncovered, 1 hour.
