Growing up I never really understood what kind of heritage came with being Arkansan. To me, Arkansas was mostly just poor country farmers and churches. And that is definitely part of it. But Arkansas is also more a cultural mixing pot then I realized, with Southern, Cajun, Mexican, and Asian influences. And there's also a creative entrepreneurial spirit, like in this article — Blackie Donnelly invented cheese dip. Burnell Austin invented fried pickles. Benjamin Fooks started selling soda out of the back of his car and made a brand famous enough that Sam Walton personally asked that it be sold in his stores. (Read the Grapette story on Wikipedia; it's pretty fascinating.) I'm sure at least part of this is our larger American heritage, but it's nice to see examples specific to Arkansas (beyond the obvious, i.e. Sam Walton).
Anyway, I know I'm rambling, but this sort of stuff has been in the back of my mind since going to Chicago last year, and today I had a Chicago dog from Sonic that doesn't come close to doing the name justice and that made me start thinking about what would be considered quintessentially Arkansan cuisine.
Final thoughts: Arkansas may not have a well-known strong unifying identity like Chicago or other cities & states, but we are creative, humble, common sense people who are more well-traveled than others would seem to think (stop me and have me tell you my stories about accents & vacations sometime). Also I need to try Possum Pie sometime: it sounds pretty good.
