Ripe ($25, 312 pp.), by Cheryl Sternman Rule, introduces a fruit-and-vegetable cookbook in a new light: arranging each assortment by color rather than season. Rule, voice behind popular food blog “5 Second Rule,” starts the book off with red edibles and eventually ends the color spectrum with white foods. The red and orange sections include oranges, cherries, pomegranates and grapefruits; the yellow and green include bananas, lemons, corn, squash and pineapple; the purple and blue follow with the more exotic blackberries, blueberries, plums and eggplant; and the book finishes with the cleansing white section that includes coconut, mushrooms, potatoes, cauliflower and garlic. Each fruit is paired with a short essay and creative recipe ideas.
