In Donuts, Edge walks us though the donut's inception as Dutch fare, the Salvation Army's wartime donuts, the invention of the donut machine, the 1950s donut-shop craze, the Krispy Kreme revolution, the appropriation by other ethnicities, and the fanatical chefs that take donuts to a new art form. Nothing encourages our sweet-tooth cravings like the donut. It is honest. It is satisfying. It is a national symbol that has survived the low carb-diet dogma and the death of the local donut shop, and it is making a comeback into the hearts of Americans.
