For more than six months, Catherine Walthers (at right) and her family ate kale in some form in at least one meal each day. She sauteed, stir-fried, braised, roasted, and massaged (yes, that’s what it’s called) the dark leafy green super food. The result is “Kale, Glorious Kale,” the fourth cookbook from the Martha’s Vineyard chef. “I learned a lot about kale and cannot say enough about how not only diverse, but delicious, it is,” says the author, who “discovered baby kale, which I really like. It’s so tasty and tender, and it holds up great to salad dressing.” Many recipes, including potato-kale latkes, and kale, celery, date, and apple salad, are accompanied by photographs from award-winning island photographer Alison Shaw. On Sept. 24, Walthers will be at Fruit Center Marketplace, 10 Bassett St., Milton, 617-696-5274, from 5:30-7 p.m. Cost is $25 and includes a tasting and signed copy of her book.
