Finished Frostbite: How Refrigeration Changed Our Food, Our Planet, and Ourselves by Nicola Twilley, co-host of the podcast Gastropod and an award winning contributor to The New Yorker. I spent a career in the food industry and even so I learned a lot from this book. The book begins with cooling as preservation in antiquity and ends with third world countries unable to feed their people with over half of their crops rotting because of no food refrigeration system. The book is filled with interesting insights, the impact of refrigeration on the environment, food waste caused by excess capacity home refrigerators that encourage over purchasing that never gets consumed, the cellular biology of produce, that fruits and vegetables continue respiration after harvest and how, chemicals and refrigeration permit out of season produce and much more. The most troubling part of the book is the bleak outlook for the planet if the ”cold chain�� is interrupted. An eye opening book
