Matthew Kenney is one of the most respected, well-known chefs in New York City – and as a native of Searsport, he’s a local boy who has done well. Kenney recently has undergone a change in his approach to his craft, however, as several years ago he adopted an organic, vegan, raw diet. This has informed his entire way of cooking, and while the menu hasn’t changed at any of his many successful restaurants in Manhattan, he has expressed his new style in his latest book, “Everyday Raw.” The book features recipes for unbaked crackers and crisps, smoothies, salads, salsas, desserts and even ice cream – none of which have been cooked, in order to retain vital nutrients and flavor. Kenney will be on hand to sign copies of “Everyday Raw,” as well as offer up samples of some of the recipes in the book, from 3 to 5 p.m. Saturday, Aug. 23, at Left Bank Books on Main Street in Searsport. Kenney is also co-author of “Raw Food/Real World: 100 Recipes to Get the Glow,” and will publish another book, “Entertaining in the Raw,” early next year. For more, call Left Bank Books at 548-6400.
