Whether it be reviving leftovers or finding purpose for that can of vegetables in your cupboard, The Everlasting Meal Cookbook will show you how to sustainably re-create dishes using food you already have. Divided by ingredient, each section delves into dozens of simple meals (pot pie can easily be turned into chowder), tips (pistachio shells make good mulch), and tricks (did you know sour heavy cream can be turned into cooking butter?). And it's all delivered in James Beard Award- winner Tamar Adler's lyrical and creative style. (HH)
