i know. it’s really southern, as i can attest to many summers in alabama at my relatives. although black cuisine has heavily influenced southern cusine, fried chicken is not exclusively black for sure.
Everyone makes fried chicken, practically, and fried fish, and cornbread. Greens are mostly a Southern thing, but not exclusively. My old relatives in Missouri - the pre-World War 2 generation - could be pretty racist, but they had a Southern-influenced country diet, just as rural black people did.
As I said above, only city people would think that menu was distinctively black.
