In 2016, Disney released a recipe called Tiana's Healthy Gumbo which caused quite a stir on the internet. But then what doesn't, right? The "gumbo" didn't start out with a roux, one of the ingredients was kale, and instead of being served over rice it was served with quinoa. Riddle me this, Batman! When is a gumbo not a gumbo? There were some defenders of the dish. After all, gumbo is less of a recipe and more of a general idea for a type of stew. But there were plenty of people who were unhappy with Disney modifying a traditional regional dish.
When I lived in Colorado Springs as a wee lad, my mother entered a cooking contest whose theme was traditional holiday dishes and prepared a fine Christmas goose with some sort of dressing. One eager entrant submitted her vegetarian pizza and much to the surprise of many participants she won. And by surprise I mean they were pissed because nobody viewed vegetarian pizza as a traditional holiday dish. (Incidentally, I suspect the entrant to be the type of person to bring a werewolf to a vampire game.)
We don't always think of it, but food is culturally imporant to us in ways beyond just tasting good.
