For his return to cookbooks after a whole decade away from them, the chef Heston Blumenthal is taking a new approach to the genre. Despite his Michelin three-star pedigree at The Fat Duck, Is This a Cookbook? is an accessible guide meant to pique home cooks’ interest in culinary adventure. The experimental Blumenthal wants his latest tome to be a low-pressure guide to the kitchen, offering simple yet innovative recipes for dishes like green gazpacho, tomato and coffee muffins and popcorn chicken with real popcorn. Ideally, for those who have found cooking to be stressful in the past, this cookbook—or non-cookbook?—brings some fun and pleasure back to the kitchen.
