If you’ve read my book Midwest Maize, you’ll know that there was a massive oyster craze in the Midwest during the mid-1800s. (And if you haven’t read it, know that there really is a connection between oysters and corn at this time.)
Anyway, once canning existed and began to become more widely available (even though cans were being cut and assembled by hand), thanks to the country’s extensive train networks, luxuries from the East Coast began to flood into the Heartland. People who had nothing else in common shared the passion for oysters, and oyster bars popped up in both large and small towns. Here is the evidence of this craze from Old Cowtown Museum.
