A century ago, the introduction of artificial refrigeration overturned millennia of dietary history, launching a new chapter in human nutrition. We could now overcome not just rot, but seasonality and geography. Tomatoes in January? Avocados in Shanghai? All possible. In Frostbite, New Yorker contributor and cohost of the award-winning podcast Gastropod Nicola Twilley takes readers on a tour of the cold chain from farm to fridge, visiting off-the-beaten-path landmarks such as Missouri’s subterranean cheese caves, the banana-ripening rooms of New York City, and the vast refrigerated tanks that store the nation’s orange juice reserves. Today, nearly three-quarters of everything on the average American plate is processed, shipped, stored, and sold under refrigeration. It’s impossible to make sense of our food system without understanding the all-but-invisible network of thermal control that underpins it. Twilley’s eye-opening book is the first to reveal how refrigeration has changed what we eat, where it’s grown, how it tastes, and—most importantly—how it affects our health and the environment.

In the developed world, we’ve reaped the benefits of refrigeration for more than a century, but the costs are catching up with us. More important, refrigeration is one of the leading contributors to climate change. As the developing world races to build a US-style cold chain, Twilley asks: Can we reduce our dependence on refrigeration? Should we? A deeply researched and entertaining dive into the most important invention in the history of food and drink, Frostbite makes the case for a recalibration of our relationship with the fridge—and how our future might depend on it.
