It’s hard to imagine that the hamburger hasn’t always existed in its present form. The origins of the burger as a staple of American cuisine trace back to White Castle, a now overlooked but still profitable player in the North American restaurant trade. Selling’em by the Sack: White Castle and the Creation of American Food is a fascinating look at the company largely responsible for creating the fast food industry. | Selling 'em by the Sack by David G.
