In about 6,500 words, British writer Sam Knight, writing in the Guardian, has published an entertaining and engaging account of why (and what and how and where) that packaged sandwich in the grocery store came to be. Oh, and who made it happen. He throws in the geography, the history, the psychology, the nationality and the mentality of packaged sandwiches. He’s got the industrial processes explained and he’s got both sides of how sandwiches changed consumers and consumers changed sandwiches.
It’s about as thorough a report as you will ever find about the lowly packaged sandwich.
