While unpacking boxes of old family books recently, Elizabeth Gilbert rediscovered a dusty, yellowed hardcover called At Home on the Range, originally written by her great-grandmother, Margaret Yardley Potter. Having only been peripherally aware of the volume, Gilbert dug in with some curiosity, and soon found that she had stumbled upon a book far ahead of its time. Part scholar and part crusader for a more open food conversation, Potter espoused the importance of farmer’s markets and ethnic food (Italian, Jewish, and German), derided preservatives and culinary shortcuts, and generally celebrated a devotion to epicurean adventures. Reading this practical and humorous cookbook, it’s not hard to see that Gilbert inherited her great-grandmother’s love of food and her warm, infectious prose.
